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 ...

Acrylate polymers belong to a group of polymers which could be referred to generally as plastics. They are noted for their transparency, resistance to breakage, and elasticity. They are also commonly known as acrylics or polyacrylates. Acrylate polymer is commonly used in cosmetics such as nail polish as an adhesive. Acrylate monomers used to form acrylate polymers are based on the structure of acrylic acid, which consists of a vinyl group and a carboxylic acid terminus. Other typical acrylate monomers are derivatives of acrylic acid, such as methyl methacrylate in which one vinyl hydrogen and the carboxylic acid hydrogen are both replaced by methyl groups, and acrylonitrile in which the carboxylic acid group is replaced by the related nitrile group. Other examples of acrylate monomers are: Methacrylates Methyl acrylate Ethyl acrylate 2-Chloroethyl vinyl ether 2-Ethylhexyl acrylate Hydroxyethyl methacrylate Butyl acrylate Butyl methacrylate TMPTA Acrylic elastomer is a general term for a type of ...

Triethanolamine (1), N-methyldiethanolamine (2) and N,N-dimethylethanolamine (3) have been used in conjunction with the 2-(2-chlorophenyl)-4,5-diphenylimidazolyl radical and triplet benzophenone to initiate the polymerisation of lauryl acrylate. The radical abstracts a hydrogen atom from the amine to generate an alpha-aminoalkyl radical. From the order of reactivity of the amines towards the lophyl (triarylimidazolyl) radical i.p. 2 ,, 1 , 3 it is concluded that hydrogen-atom abstraction occurs rather than electron followed by proton transfer. The imidazolyl radicals abstract hydrogen from thiols in a similar fashion more effectively to give thiyl radicals which initiate polymerisation of the acrylate. By following the progress of the polymerisation reactions by RTIR spectroscopy, it was concluded that the effectiveness of the amines to reduce oxygen inhibition is 1 , 3 , 2. The ability of the amines to act as synergists in the polymerisation of thin films of lauryl acrylate initiated by lophyl ...
The synthesis of various esters of alpha-hydroxymethylacrylate are summarized along with a brief description of their properties and polymerizability. Polymer characterization is given, including thermal behavior, solubility and spectroscopic properties. Derivatives of the acrylates are generated through reaction of the alcohol group to give halides, esters, ethers, and ether dimers. The last, along with additional multifunctional acrylates generated through the chemistry inherent in the synthetic approach, allow formation of a number of cyclopolymers, Michael polyadducts, and crosslinked systems.

The development of biocompatible polymers using thiol-acrylate Michael addition reactions between not only acrylates and thiols but also between amines and acrylates were demonstrated. The synthesis of an in situ tertiary amine catalyst initiates the propagation steps of the polymerization process by subsequently reacting with trimethylolpropane tris (3-mercaptopropionate) (TMPTMP). A few notable characteristics of this reaction are tunable gel times, the capability of reaching high polymer conversion and suitable mechanical strength. With addition of hydroxyapatite to the polymeric phase and foaming, a porous bone composite was produced. Further osteogenisis and in vivo work using the PETA-co-TMPTMP (HA) composite material was analyzed. The PETA-co-TMPTMP-co-TMTMP with 20%HA showed an increase in osteogenic potential higher than the FDA approved PCL over the 21-day study. The rats did not exhibit any severe systemic responses from the polymer implant, and an increase in bone growth was observed for the

The propionate, or propanoate ion, is C2H5COO− (the conjugate base of propionic acid). A propionic, or propanoic, compound is a small salt or ester of propionic acid. In these compounds, propionate is often written in shorthand, as CH3CH2CO2 or simply EtCO2. Propionates should not be confused with propenoates (commonly known as acrylates), the ions/salts/esters of propenoic acid (also known as 2-propenoic acid or acrylic acid). Propionate is observed to be among the most common short-chain fatty acids produced by human gut microbiota in response to indigestible carbohydrates (fiber) in the diet.[2] A study in mice suggests that propionate is produced by the bacteria of the genus Bacteroides in the gut, and that it offers some protection against Salmonella there.[3] ...

Regardless of whether your warhead is reversible or not, it is important that different members of the library have similar reactivities: if the inherent reactivities of the fragments are different, it will be difficult to distinguish inherent binding energies from chemical reactivities. One of the problems with acrylamides is that subtle changes in chemical structures can have dramatic effects on intrinsic reactivities. The new paper compares rate constants of two acrylamides reacting with a low molecular-weight thiol, and finds that one reacts 2,000-fold faster than the other. The researchers tested three other classes of electrophiles - vinylsulfonamides, aminomethyl methyl acrylates, and methyl vinylsulfones - and found that these had narrower ranges of reactivity. They chose acrylates and built a set of 100 acrylate-modified fragments. Happily, when 50 of these were tested for reactivity, there was only a 2.4-fold difference between the most reactive and the least reactive members ...
The radical addition co-polymerisation 2-hydroxyethylmethacrylate and butylacrylate is carried out in a continuously operating Buss-Kneader. To calculate temperature profiles over the length of the kneader the heal balance is solved. For the heat transfer coefficient a model based on the penetration theory, is used. This model is experimentally verified. The reaction kinetics of the radical addition polymerisation are studied in a differential scanning calorimeter. The polymerisation kinetics are modeled using non-stationary radical concentrations. The calculated temperature profiles over the length of the Buss-Kneader are a good approximation of the experimental data.

In previous investigations, the authors have examined the adsorption of albumin, immunoglobulin, and fibrinogen to a series of acrylate polymers with different backbone and side-group flexibility. The authors showed that protein adsorption to acrylates with high flexibility, such as poly(lauryl methacrylate) (PLMA), tends to preserve native conformation. In the present study, the authors have continued this work by examining the conformational changes that occur during the binding of complement factor 3 (C3) and coagulation factor XII (FXII). Native C3 adsorbed readily to all solid surfaces tested, including a series of acrylate surfaces of varying backbone flexibility. However, a monoclonal antibody recognizing a "hidden" epitope of C3 (only exposed during C3 activation or denaturation) bound to the C3 on the rigid acrylate surfaces or on polystyrene (also rigid), but not to C3 on the flexible PLMA, indicating that varying degrees of conformational change had occurred with binding to different ...

Ian Davenport, President of Davenport International Associates LLC said the US acrylic acid supply problems of 2010 are now behind us with American Acryls running well, Dow Deer Park operating at high rates and new investments planned here and at Clear Lake. Economic reasons for not making SAP had diminished due to the downturn-related decline in demand for acrylates in paints. New SAP capacity being built in the East will raise annual global output from around 2 million tonnes to 2.8 million tonnes by 2014. 230,000 tonnes of this will be in China (San Dia, BASF and Danson), 108,000 tonnes in Korea (LG Chemical), 90,000 tonnes in Indonesia (Nippon Shokubai) and 84,000 tonnes in Japan (NS and Sumitomo Seika). Evonik will start an 80,000 tonne SAP plant in Saudi Arabia, and BASF are putting a 60,000 tonne plant into Brazil. The growth is driven by the major diaper producers (KC, P&G, SCA and Unicharm) who will use 50% of the increased production in responding to the increasing demand for diapers ...
