Reactive continuous rods of macroporous poly(glycidyl methacrylate-co-ethylene dimethacrylate) were prepared within the confines of a stainless steel column. Then papain was immobilized on these monoliths either directly or linked by a spacer arm. In a further step, a protein A affinity column was used for the characterization of the digestion products of human immunoglobulin G (IgG) by papain. The results showed that papain immobilized on the monolithic rod through a spacer arm exhibits higher activity for the digestion of human IgG than that without a spacer arm. The apparent Michaelis-Menten kinetic constants of free and immobilized papain, K-m and V-max, were determined. The digestion conditions of human IgG with free and immobilized papain were optimized. Comparison of the thermal stability of free and immobilized papain showed that the immobilized papain exhibited higher thermal stability than the free enzyme. The half-time of immobilized papain reaches about a week under optimum pH and ...

A new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. Mathematical correlations and the kinetics used in this model are based on the polymeric multigrain and the multilayer models, respectively. In the modeling, multiplicity of active site using different kinetics parameters as well as deactivation of catalyst during the polymerization have been considered,. Moreover, it considers mass transfer effects on polymerization characteristics. The Effects of physico-chemical aspects of catalyst associated with the polymerization in slurry phase are also considered in this model. In addition, the effects of more important model parameters including time step, number of layers and number of active sites on the produced polymer
Novel method of making a semi-permeable membrane having a perhalogenated olefin substrate by grafting onto such substrate acrylic acid or other hydrophilic acid groups. The grafting is accomplished by forming a grafting medium comprising water, olefinically unsaturated hydrophilic acid moiety and an inorganic polymerization inhibitor for the homopolymerization of said hydrophilic acid which is a salt of a polyvalent metal; immersing perhalogenated olefin polymer substrate in the grafting medium; and then subjecting such to ionizing radiation sufficient to cause grafting of said hydrophilic acid onto said perhalogenated olifin polymer substrate.
A complex comprises organoborane and polyamine. The polyamine is the reaction product of a diprimary amine-terminated material and a material having at least two groups reactive with primary amine. The complexes are useful in systems for initiating the polymerization of acrylic monomer, which systems further include a material reactive with amine. Polymerizable acrylic monomer compositions useful as adhesives can be prepared.

en] Copolymerization of binary mixtures of alkyl (meth)acrylates has been initiated in toluene by a mixed complex of lithium silanolate (s-BuMe2SiOLi) and s-BuLi (molar ratio , 21) formed in situ by reaction of s-BuLi with hexamethylcyclotrisiloxane (D3). Fully acrylate and methacrylate copolymers, i.e., poly(methyl acrylate-co-n-butyl acrylate), poly(methyl methacrylate-co-ethyl methacrylate), poly(methyl methacrylate-co-n-butyl methacrylate), poly(methyl methacrylate-co-n-butyl methacrylate), poly(isobornyl methacrylate-co-n-butyl methacrylate), poly(isobornyl methacrylate-co-n-butyl methacrylate) of a rather narrow molecular weight distribution have been synthesized. However, copolymerization of alkyl acrylate and methyl methacrylate pairs has completely failed, leading to the selective formation of homopoly(acrylate). As result of the isotactic stereoregulation of the alkyl methacrylate polymerization by the s-BuLi/s-BuMe2SiOLi initiator, highly isotactic random and block copolymers of ...

Copolymers of glycidyl methacrylate and allyl glycidyl ether having pendant epoxy groups, having an inherent viscosity of at least about 0.25, preferably within the range of about 0.25 to about 0.38, and an epoxy equivalent of at least about 0.65 epoxide equivalent per 100 g. of polymer are provided which upon admixture with a radiation-sensitive aryldiazonium salt provide compositions which exhibit improved sensitivity, curing rates and other properties. Articles for recording and storing information from a laser source and other articles such as microfilm are derived from such compositions by subjecting a coated substrate to an energy source of sufficient intensity to decompose the radiation-sensitive catalyst and thus effect polymerization via the epoxy groups of the copolymer.
We present in this category the monomers used for biomaterials research classified according to their chemical structures such as acrylic monomers, lactone monomers, dithiol monomers, and diisocyanate monomers. Among them acrylic monomers contain largest number of products and are often utilized for biomaterials or biocompatible materials research, using conventional radical polymerization or controlled radical polymerization. In addition to the common monomers for biomaterials research including 2-hydroxyethyl methacrylate (HEMA) [M0085]1) and N-isopropylacrylamide (NIPAAm) [I0401]2), TCI has zwitterionic monomers or monomers with reactive functional groups useful for conjugation with proteins or peptides present in our catalog. Zwitterionic monomers contain both cationic and anionic groups in the same molecule. Common zwitterionic monomer structures include phosphobetaines, sulfobetaines, and carboxybetaines.3,4) One of the phosphobetaine zwitterionic monomers, 2-(methacryloyloxy)ethyl 2-

There is an increasing demand for new materials in biomedical applications with material properties that are highly specific for each application area. The search for new materials requires the creation of materials with suitable mechanical properties, functionalities, three-dimensional structures and a controlled degradation profile. The focus of the work described in this thesis has been on the synthesis of functional degradable aliphatic polyesters, on the design of porous scaffolds and on their synthesis with bio-safe catalyst/initiator systems. An unsaturated aliphatic polyester has been synthesized by condensation polymerization to produce poly(but-2-ene-1,4-diyl malonate) (PBM), which was applicable as a cross-linked network and as a macro-co-initiator for the ring-opening polymerization (ROP) of cyclic ester monomers. The method of preparation of PBM was simple and straightforward and there was no need to purify the monomers or add a catalyst. PBM was successfully cross-linked with ...
Photopolymerizable compositions are described containing a polymerizable ethylenically unsaturated monomer, a photoinitiator or initiator system, and selected acidic polymeric binders. The organic binder mixture contains a compound chosen from each of two selected classes. These photopolymerizable compositions yield superior processability, i.e., on developing and stripping, in solely aqueous alkaline media devoid of organic solvents, decreased softness and/or tackiness, and improved adhesion when compared to the prior art. The compositions are particularly useful for preparing photoresists.

Is there actually a permanent cure for hair loss? This is what millions of people are asking right now. There are currently many different procedures, products, and medications you can use to grow hair. The tips below will tell you what works and what doesnt work to grow hair.. If you color your hair, try not to color it too frequently. When you color your hair frequently, you are not allowing it the time it needs to recover from the last coloring session. You should aim for keeping a six to eight week gap between each time that you color it.. Use a conditioner on your hair that will allow it to rebuild nutrients and be more manageable. Conditioner can strengthen the hair as well as make brushing or combing less damaging to the hair. Massage vigorously when conditioning to stimulate blood flow which will prompt the hair to be more responsive to conditioning.. You want to avoid excessive alcohol usage if you want to prevent hair loss. It is a medical fact that damage to the liver can cause hair ...
