A clearance model of inhaled man-made fibers in rat lungs. (1/1075)

A clearance model of inhaled man-made fibers (MMFs) was developed, and the calculated fiber numbers and dimensions were compared with the experimental ones using a glass fiber (GF), ceramic fiber (RF1) and two potassium octatitanate whiskers (PT1, TW). If the translocation rate by macrophages is constant and the effect of dissolution and disintegration can be ignored, the fiber number is expected to decrease exponentially with time. In the experimental study, however, the fiber number did not always decrease exponentially. In the case of RF1, the fiber number decreased almost exponentially and the diameter decreased linearly with the time. The clearance rate constant of GF during 3 to 6 months after the end of one-month exposure was greater than that during 1 to 3 months. On the contrary, the clearance rate constants of PT1 and TW during 1 to 6 months were greater than next six months. The diameter and the length of GF did not change significantly. The fiber length of PT1 tends to become longer with time although the diameter did not change significantly. Our theoretical model gives a satisfactory fit to these experimental results.  (+info)

Metabolic engineering of poly(3-hydroxyalkanoates): from DNA to plastic. (2/1075)

Poly(3-hydroxyalkanoates) (PHAs) are a class of microbially produced polyesters that have potential applications as conventional plastics, specifically thermoplastic elastomers. A wealth of biological diversity in PHA formation exists, with at least 100 different PHA constituents and at least five different dedicated PHA biosynthetic pathways. This diversity, in combination with classical microbial physiology and modern molecular biology, has now opened up this area for genetic and metabolic engineering to develop optimal PHA-producing organisms. Commercial processes for PHA production were initially developed by W. R. Grace in the 1960s and later developed by Imperial Chemical Industries, Ltd., in the United Kingdom in the 1970s and 1980s. Since the early 1990s, Metabolix Inc. and Monsanto have been the driving forces behind the commercial exploitation of PHA polymers in the United States. The gram-negative bacterium Ralstonia eutropha, formerly known as Alcaligenes eutrophus, has generally been used as the production organism of choice, and intracellular accumulation of PHA of over 90% of the cell dry weight have been reported. The advent of molecular biological techniques and a developing environmental awareness initiated a renewed scientific interest in PHAs, and the biosynthetic machinery for PHA metabolism has been studied in great detail over the last two decades. Because the structure and monomeric composition of PHAs determine the applications for each type of polymer, a variety of polymers have been synthesized by cofeeding of various substrates or by metabolic engineering of the production organism. Classical microbiology and modern molecular bacterial physiology have been brought together to decipher the intricacies of PHA metabolism both for production purposes and for the unraveling of the natural role of PHAs. This review provides an overview of the different PHA biosynthetic systems and their genetic background, followed by a detailed summation of how this natural diversity is being used to develop commercially attractive, recombinant processes for the large-scale production of PHAs.  (+info)

Reduction of cell lysate viscosity during processing of poly(3-hydroxyalkanoates) by chromosomal integration of the staphylococcal nuclease gene in Pseudomonas putida. (3/1075)

Poly(3-hydroxyalkanoates) (PHAs) are biodegradable thermoplastics which are accumulated by many bacterial species in the form of intracellular granules and which are thought to serve as reserves of carbon and energy. Pseudomonas putida accumulates a polyester, composed of medium-side-chain 3-hydroxyalkanoic acids, which has excellent film-forming properties. Industrial processing of PHA involves purification of the PHA granules from high-cell-density cultures. After the fermentation process, cells are lysed by homogenization and PHA granules are purified by chemical treatment and repeated washings to yield a PHA latex. Unfortunately, the liberation of chromosomal DNA during lysis causes a dramatic increase in viscosity, which is problematic in the subsequent purification steps. Reduction of the viscosity is generally achieved by the supplementation of commercially available nuclease preparations or by heat treatment; however, both procedures add substantial costs to the process. As a solution to this problem, a nuclease-encoding gene from Staphylococcus aureus was integrated into the genomes of several PHA producers. Staphylococcal nuclease is readily expressed in PHA-producing Pseudomonas strains and is directed to the periplasm, and occasionally to the culture medium, without affecting PHA production or strain stability. During downstream processing, the viscosity of the lysate from a nuclease-integrated Pseudomonas strain was reduced to a level similar to that observed for the wild-type strain after treatment with commercial nuclease. The nuclease gene was also functionally integrated into the chromosomes of other PHA producers, including Ralstonia eutropha.  (+info)

Production of poly(3-hydroxybutyric acid-co-4-hydroxybutyric acid) and poly(4-hydroxybutyric acid) without subsequent degradation by Hydrogenophaga pseudoflava. (4/1075)

A Hydrogenophaga pseudoflava strain was able to synthesize poly(3-hydroxybutyric acid-co-4-hydroxybutyric acid) [P(3HB-co-4HB)] having a high level of 4-hydroxybutyric acid monomer unit (4HB) from gamma-butyrolactone. In a two-step process in which the first step involved production of cells containing a minimum amount of poly(3-hydroxybutyric acid) [P(3HB)] and the second step involved polyester accumulation from the lactone, approximately 5 to 10 mol% of the 3-hydroxybutyric acid (3HB) derived from the first-step culture was unavoidably reincorporated into the polymer in the second cultivation step. Reincorporation of the 3HB units produced from degradation of the first-step residual P(3HB) was confirmed by high-resolution 13C nuclear magnetic resonance spectroscopy. In order to synthesize 3HB-free poly(4-hydroxybutyric acid) [P(4HB)] homopolymer, a three-stage cultivation technique was developed by adding a nitrogen addition step, which completely removed the residual P(3HB). The resulting polymer was free of 3HB. However, when the strain was grown on gamma-butyrolactone as the sole carbon source in a synthesis medium, a copolyester of P(3HB-co-4HB) containing 45 mol% 3HB was produced. One-step cultivation on gamma-butyrolactone required a rather long induction time (3 to 4 days). On the basis of the results of an enzymatic study performed with crude extracts, we suggest that the inability of cells to produce 3HB in the multistep culture was due to a low level of 4-hydroxybutyric acid (4HBA) dehydrogenase activity, which resulted in a low level of acetyl coenzyme A. Thus, 3HB formation from gamma-butyrolactone is driven by a high level of 4HBA dehydrogenase activity induced by long exposure to gamma-butyrolactone, as is the case for a one-step culture. In addition, intracellular degradation kinetics studies showed that P(3HB) in cells was completely degraded within 30 h of cultivation after being transferred to a carbon-free mineral medium containing additional ammonium sulfate, while P(3HB-co-4HB) containing 5 mol% 3HB and 95 mol% 4HB was totally inert in interactions with the intracellular depolymerases. Intracellular inertness could be a useful factor for efficient synthesis of the P(4HB) homopolymer and of 4HB-rich P(3HB-co-4HB) by the strain used in this study.  (+info)

Analyses of a polyhydroxyalkanoic acid granule-associated 16-kilodalton protein and its putative regulator in the pha locus of Paracoccus denitrificans. (5/1075)

The polyhydroxyalkanoic acid (PHA) granule-associated 16-kDa protein (GA16 protein) of Paracoccus denitrificans was identified, and its corresponding gene was cloned and analyzed at the molecular level. The N-terminal amino acid sequence of GA16 protein revealed that its structural gene is located downstream from the PHA synthase gene (phaCPd) cloned recently (S. Ueda, T. Yabutani, A. Maehara, and T. Yamane, J. Bacteriol. 178:774-779, 1996). Gene walking around phaCPd revealed two new open reading frames (ORFs) possibly related to PHA synthesis, one of which was the phaPPd gene, encoding GA16 protein, and the other was the phaRPd gene, encoding a protein that is putatively involved in the regulation of the expression of phaPPd. Overproduction of PhaPPd was observed in Escherichia coli carrying phaPPd, but the overproduction was not observed in the presence of phaRPd. Coexpression of phaPPd and PHA biosynthesis genes in E. coli caused increases in both the number of poly-(3-hydroxybutyric acid) (PHB) granules and PHB content and caused decreases in both the size of the granules and the molecular weight of PHB. GA16 protein was considered a phasin protein. The phaRPd gene had significant similarities to stdC, a possible transcriptional factor of Comamonas testosteroni, as well as to other ORFs of unknown function previously found in other PHA-synthetic bacteria.  (+info)

Paracrine immunotherapy with interleukin-2 and local chemotherapy is synergistic in the treatment of experimental brain tumors. (6/1075)

Potent immune responses against malignant brain tumors can be elicited by paracrine intracranial (i.c.) immunotherapy with interleukin (IL)-2. Additionally, i.c. delivery of carmustine via biodegradable polymers has been shown to significantly prolong survival in both animal models and clinical trials. In this study, we show that the combination of paracrine immunotherapy, with nonreplicating genetically engineered tumor cells that produce IL-2, and local delivery of chemotherapy by biodegradable polymers prolongs survival in a synergistic manner in mice challenged intracranially with a lethal murine brain tumor. Animals receiving IL-2-transduced cells and polymers containing 10% 1,3-bis(2-chloroethyl)-1-nitrosourea had significantly improved survival compared with animals receiving IL-2-transduced cells or 10% 1,3-bis(2-chloroethyl)-1-nitrosourea alone. Median survival for the control group was 19 days. Survival in animals receiving IL-2-transduced cells and 1% carboplatin-containing polymers was also significantly improved compared with either therapy alone. Histopathological examination on day 14 of animals receiving combination treatment showed rare degenerating tumor cells. In addition to tissue necrosis surrounding the polymer, a marked inflammatory reaction was observed. In long-term survivors (all animals receiving combination treatment), no tumor was observed and the inflammatory reaction was completely resolved. The brains of animals receiving combination therapy showed both tissue necrosis due to local chemotherapy and strong inflammation due to paracrine immunotherapy. The demonstration of synergy between paracrine IL-2 and local i.c. delivery of antineoplastic drugs is novel and may provide a combined treatment strategy for use against both primary and metastatic i.c. tumors.  (+info)

Health hazards in the production and processing of some fibers, resins, and plastics in Bulgaria. (7/1075)

Results of the toxicological studies of working conditions, general and professional morbidity, and complex examinations carried out on workers engaged in the production of polyamides, polyacrylonitrile fibers, polyester fibers and poly (vinyl chloride) resin, urea-formaldehyde glue, glass fibre materials and polyurethane resins are given.

Removal of endotoxin during purification of poly(3-hydroxybutyrate) from gram-negative bacteria. (8/1075)

Poly(3-hydroxybutyrate) (PHB) was produced by cultivating several gram-negative bacteria, including Ralstonia eutropha, Alcaligenes latus, and recombinant Escherichia coli. PHB was recovered from these bacteria by two different methods, and the endotoxin levels were determined. When PHB was recovered by the chloroform extraction method, the endotoxin level was less than 10 endotoxin units (EU) per g of PHB irrespective of the bacterial strains employed and the PHB content in the cell. The NaOH digestion method, which was particularly effective for the recovery of PHB from recombinant E. coli, was also examined for endotoxin removal. The endotoxin level present in PHB recovered by 0.2 N NaOH digestion for 1 h at 30 degrees C was higher than 10(4) EU/g of PHB. Increasing the digestion time or NaOH concentration reduced the endotoxin level to less than 1 EU/g of PHB. It was concluded that PHB with a low endotoxin level, which can be used for various biomedical applications, could be produced by chloroform extraction. Furthermore, PHB with a much lower endotoxin level could be produced from recombinant E. coli by simple NaOH digestion.  (+info)

Abstract Peripheral nerves possess the capacity of self-regeneration after traumatic injury. Transected peripheral nerves can be bridged by direct surgical coaptation of the two nerve stumps or by interposing autografts or biological (veins) or synthetic nerve conduits (NC). NC are tubular structures that guide the regenerating axons to the distal nerve stump. Early synthetic NC have primarily been made of silicone because of the relative flexibility and biocompatibility of this material and because medical-grade silicone tubes were readily available in various dimensions. Nowadays, NC are preferably made of biodegradable materials such as collagen, aliphatic polyesters, or polyurethanes. Although NC assist in guiding regenerating nerves, satisfactory functional restoration of severed nerves may further require exogenous growth factors. Therefore, authors have proposed NC with integrated delivery systems for growth factors or growth factor,producing cells. This article reviews the most important ...

0002] Non-aqueous dispersions are known, as are microparticles produced by non-aqueous dispersion techniques. Typically, non-aqueous dispersions are prepared by the free radical addition polymerization of ethylenically unsaturated monomers in a hydrocarbon rich dispersing medium. The polymerization is carried out in the presence of a steric stabilizer, a portion of which is soluble in the dispersing medium and a portion of which is associated with the dispersed polymer; the dispersed polymer is insoluble in the dispersing medium. The steric stabilizer can be physically or chemically bound to the dispersed polymer. The portion of the steric stabilizer that is soluble in the dispersing medium is typically an aliphatic polyester or an acrylic polymer that is prepared from aliphatic monomers. There are several drawbacks with non-aqueous dispersions produced using these types of stabilizers due to the large difference in polarity, compatibility and solubility characteristics between the stabilizer ...
0127]Generally, if the degree of brilliance is high, normal reflectivity becomes large and the surface appears glossy; conversely, if the degree of brilliance is low, normal reflectivity also becomes low, and the surface appears to be rough. Also in reflective films, those with high normal reflectivity tend to have high front brightness and satisfactory light reflection capabilities. If the degree of brilliance on the side of the surface for reflection use of the present reflective film at 60° is in the range of 50 to 95, satisfactory light reflection capabilities, and in particular satisfactory brightness, are obtained. Such effects appear particularly notably in the case of a constitution in which, sequentially from the liquid crystal side in the internal constitution of a liquid crystal television, a brightness improvement sheet, a diffusion sheet, a diffusion plate, a cold cathode tube and a reflective film are layered. Conversely, if the degree of brilliance is below 50, diffuse ...

After conjugation of terminal carboxylic acid groups of polyester to polyethylene glycol (PEG), the resulting polymer ...
Previous studies (24, 31) that investigated the effect of PhaP on PHB accumulation in recombinant E. coli carrying pha from C. necator have shown an increase in polymer accumulation and a higher number of smaller PHA granules in strains carrying phaP. York et al. (31) reported a 100% increase in polymer production in 105-h flask cultures in LB containing 2% glucose. We analyzed the effect of phaP of Azotobacter sp. strain FA8 on PHB accumulation and bacterial growth in recombinant E. coli carrying the pha-synthesizing genes from this strain. As expected, the cells carrying PhaP accumulated more polymer. When the effect of PhaP on cell growth was first analyzed in flask cultures grown in minimal medium with lactose, no differences were observed, but when cells were grown in conditions in which higher cell densities were achieved, those carrying phaP grew more and accumulated more PHB. When cultures were grown in a bioreactor using glycerol, the differences observed were greater. The increase in ...
There is an increasing need for synthetic bone substitute materials that decrease the need for allografts and autografts. In this study, composites of β-TCP and a biodegradable poly(L-lactide-co-ε-caprolactone) were manufactured using extrusion to form biodegradable composites with high β-TCP contents for osteoconductivity. The hydrolytic degradation of the composites containing 0, 10, 20, 35 and 50% of β-TCP was studied in vitro for 52 weeks. During the study, it was observed that β-TCP did not have an effect on the degradation rate of the polymer matrix. However, the crystallinity of the materials increased throughout the test series and changes in Tgs were also observed as the comonomer ratio of the polymer matrix changed as the degradation proceeded. The results show that the materials have desirable degradation properties and, thus, possess great potential as bioabsorbable and osteoconductive bone filling materials ...

3-hydroxybutyric acid) (PHB) is the most commonly produced polyhydroxyalkanoate formed naturally inside many genera of bacteria and archaea when nutrients are limited and a carbon-source is available in excess. These water-insoluble biopolyester spherical beads in the size range of 20-800 nm can be recombinantly produced by insertion of the required PHB biosynthesis genes into alternative bacterial hosts and then culturing the organisms under suitable conditions. A gene fusion can also be made to enable production of PHB beads which display the selected proteins abundantly at the surface of the bead. Vaccines are needed which stimulate cell-mediated immunity and are effective at reducing intracellular infections such as tuberculosis, neosporosis and many viral infections. These diseases are responsible for a huge burden to human and animal health. Particulate vaccines target antigen presenting cells and cellular immune responses to protein antigens are enhanced when particulate vaccines are ...

Stem cell and tissue engineering offer us with a unique opportunity to research and develop new therapies for treating various diseases that are otherwise incurable using traditional medicines. However, development of these new therapies replies upon the establishment of in vitro cell culture and differentiation systems that mimic in vivo microenvironments required for cell-cell and cell-ECM interaction. The development of these cell culture systems depends upon the identification of appropriate biomaterials and cell sources. Biomaterials should be carefully selected and fabricated into scaffolds for supporting cell growth and differentiation. In this study, we explored the fabrication of 3D electrospun nanofiber scaffolds and demonstrated the feasibility of using these scaffolds for supporting cell growth. The material that we used for scaffold fabrication is a polymer, polycaprolactone (PCL). We discovered that the electrospun PCL nanofibers are highly hydrophobic, unsuitable for cell growth. The
Hybrid constructs represent substantial progress in tissue engineering (TE) towards producing implants of a clinically relevant size that recapitulate the structure and multicellular complexity of the native tissue. They are created by interlacing printed scaffolds, sacrificial materials, and cell-laden hydrogels. A suitable biomaterial is a polycaprolactone (PCL); however, due to the higher viscosity of this biopolymer, three-dimensional (3D) printing of PCL is slow, so reducing PCL print times remains a challenge. We investigated parameters, such as nozzle shape and size, carriage speed, and print temperature, to find a tradeoff that speeds up the creation of hybrid constructs of controlled porosity. We performed experiments with conical, cylindrical, and cylindrical shortened nozzles and numerical simulations to infer a more comprehensive understanding of PCL flow rate. We found that conical nozzles are advised as they exhibited the highest shear rate, which increased the flow rate. When working at a
Thermo-responsive multiblock poly(ester urethane)s comprising poly(ε-caprolactone) (PCL), poly(ethylene glycol) (PEG), and poly(propylene glycol) (PPG) segments were synthesized. The copolymers were characterized by GPC, NMR, FTIR, XRD, DSC and TGA. Water-swelling analysis carried out at different temperatures revealed that the bulk hydrophilicity of the copolymers could be controlled either by adjusting the composition of the copolymer or by changing the temperature of the environment. These thermo-responsive copolymer films formed highly swollen hydrogel-like materials when soaked in cold water and shrank when soaked in warm water. The changes are reversible. The mechanical properties of the copolymer films were assessed by tensile strength measurement. These copolymers were ductile when compared to PCL homopolymers. Youngs modulus and the stress at break increased with increasing PCL content, whereas the strain at break increased with increasing PEG content. The results of the cytotoxicity ...
Early buyers will receive 10% customization on reports.. Increasing stringent regulations on VOC emissions leading to the development of eco-friendly technologies, such as powder coatings and waterborne coatings, are replacing solvent-borne coatings. This in turn drives the demand for saturated polyester resin, as they are one of the principal resin systems for powder coatings, and show high performance owing to superior mechanical properties. These factors contribute to the growth of the saturated polyester resin market.. Liquid SPR accounted for the largest share of saturated polyester resin market. Liquid SPR are primarily used for coil & can coatings and other uses, such as industrial paints, automotive paints, and 2k PU coatings. The growing demand for trim, soffit, fascia, other aluminum products, and commercial construction products, such as metal roofing, cladding, and HVAC equipment is driving the coil coatings market, which in turn drives the demand for liquid saturated polyester ...
To: [email protected] Subject: Re: hull fairing From: Kevin [email protected] Date: Sun, 12 Sep 1999 00:28:23 -0400 Just a few facts that I know concerning the comparison of polyester resins to epoxy: Polyester is not an epoxy. It is a complete resin system that will slowly polymerize when its solvent is evaporated - though this may take months. That is why MEKP is added. It is a catalyst - not a component of the resin system - that speeds up polymerization, or curing. Epoxy is a true two-part resin system in that polymerization will not occur - over any length of time - unless the two components are mixed. Why epoxy is a better barrier coat than polyester and why epoxy doesnt blister... Epoxy is 100% solids (high quality epoxy, anyway, such as WEST, System 3, and others) meaning that there are no solvents - the lack of solvents is why epoxy resin and hardener do not have much of an odor, though some odor. The weight of cured epoxy will be the same as when it was liquid. Polyester resins ...

Poly-ε-caprolactone (PCL) is chemically produced on an industrial scale in spite of the need for hazardous peracetic acid as an oxidation reagent. Although Baeyer-Villiger monooxygenases (BVMO) in principle enable the enzymatic synthesis of ε-caprolactone (ε-CL) directly from cyclohexanone with molecular oxygen, current systems suffer from low productivity and are subject to substrate and product inhibition. The major limitations for such a biocatalytic route to produce this bulk chemical were overcome by combining an alcohol dehydrogenase with a BVMO to enable the efficient oxidation of cyclohexanol to ε-CL. Key to success was a subsequent direct ring-opening oligomerization of in situ formed ε-CL in the aqueous phase by using lipase A from Candida antarctica, thus efficiently solving the product inhibition problem and leading to the formation of oligo-ε-CL at more than 20 g L(-1) when starting from 200 mM cyclohexanol. This oligomer is easily chemically polymerized to PCL ...

Polyhydroxybutyrate (PHB) is one of the polyhydroxyalkanoates (PHAs) which has biodegradable and biocompatible properties. They are adopted in the biomedical field, in, for example, medical implants and drug delivery carriers. This study seeks to promote the production of PHB by Vibrio sp. BM-1, isolated from a marine environment by improving constituents of medium and implementing an appropriate fermentation strategy. This study successfully developed a glycerol-yeast extract-tryptone (GYT) medium that can facilitate the growth of Vibrio sp. BM-1 and lead to the production of 1.4 g/L PHB at 20 h cultivation. This study also shows that 1.57 g/L PHB concentration and 16% PHB content were achieved, respectively, when Vibrio sp. BM-1 was cultivated with MS-GYT medium (mineral salts-supplemented GYT medium) for 12 h. Both cell dry weight (CDW) and residual CDW remained constant at around 8.2 g/L and 8.0 g/L after the 12 h of cultivation, until the end of the experiment. However, both 16% of PHB content and

There are substantial environmental concerns with the recycling of polyester right now. Most polyester contains antimony which is not a benign chemical - it is a likely carcinogen, among other issues. Recycling polyester releases encapsulated antimony, thus creating antimony trioxide, which has a toxicity profile less sanguine even than antimonys. If your green desire is to help stem the use of industrial chemicals and their pollution of the earth - and of people - this is a step you would choose to avoid. Thanks to the cradle to cradle people, antimony free polyester does exist. Antimony free polyester fabrics are available. Unfortunately, although antimony free polyester - that is, non-toxic polyester (and there is controversy about whether the antimony is a threat to humans during use and before end of life) - does exist, there is no viable program for recycling it and keeping it segregated from other types of polyester right now. In fact, there is no viable program for the recycling of ...
1. Introduction. Biopolymers derived from renewable resources have attracted growing attention over the last decades as biocompatible and biodegradable alternatives to petrochemical-based plastics.1-5 An excellent example of such a biodegradable polymer is polylactide (PLA), which can be obtained by ring-opening polymerization (ROP) of lactide monomers. PLAs display desirable mechanical, optical and chemical properties such as optical transparency, ease of processing and ease of microbial decomposition or degradation. Due to these unique features, PLAs have wide range of applications in food packaging6a as well as in pharmaceutical industries, tissue engineering and drug delivery devices.6b,c. The ring-opening polymerization of lactides can be catalyzed by organometallic initiators,7 organocatalysts8 as well as enzymes.9 Organometallic-based catalysts have several advantages that include proper control of polymer stereo-regularity and molecular weight distribution.10-12 Furthermore, it is ...
Reactive blends of polypropylene and unsaturated polyester with different compositions were prepared by melt processing using dicumyl peroxide (DCP) as initiator in a plasticoder. Rheological Characteristics of the blends were studied as a function of unsaturated polyester concentration over a range of strain rate. The possibility of forming a graft polymer increased with increasing the unsaturated polyester content. Change in viscosity behavior of the blends was a result of the competing reactions of degradation and grafting.

By Renard, E Langlois, V; Guerin, P Polyhydroxyalkanoates (PHAs) form an enlarged family of biopolyesters, which are biocompatible, biodegradable and non- toxic. Polyhydroxyalkanoates biodegradation corresponds to a hydrolysis involving endo- or exo-enzymatic systems in the breaking cleavage of esters bonds. This type of degradation is needed for environmental applications. In the case of therapeutic and biomedical uses, a simple hydrolysis is required. Hydrolytic degradation of PHAs is not evident as shown on poly(3- hydroxyoctanoate) (PHO) and is depending on the structure of the polyester and more particularly on the nature of the side chains. In some cases, blending with others polymers has decreased PHAs crystallinity and has made easier hydrolysis. Another route consists in the preparation of unsaturated PHAs which can be chemically modified. Pendant double bonds have been turned into carboxylic, hydroxyl or epoxy groups. Moreover these reactive functions were used for grafting oligomers ...
