Polyethylene glycol acrylate

Polymers such as the acrylic PVM/MA copolymer are added to prevent bacteria from breaking down pyrophosphates. Other long polymers used are polyethylene glycol (PEG) in various weights (PEG-6, PEG-8, PEG-40, etc.), and polypropylene glycol (PPG). 

Cellulosic, polyester, and acrylic fibers lubricated with a surfactant-based oiling composition containing an organic phosphorus ester neutralized with an amine showed less pilling, good antistatic properties, and anticorrosiveness. The phosphorus ester salts were hexyl phosphate trimethylamine salt, dodecamethy-lene caproate phosphonate ethylamine salt, and polyethylene glycol dodecyl ether phosphate dimethylamine salt [262]. 

II. B polyethylene glycol, ethylene oxide, polystyrene, diisocyanates (urethanes), polyvinylchloride, chloroprene, THF, diglycolide, dilac-tide, <5-valerolactone, substituted e-caprolactones, 4-vinyl anisole, styrene, methyl methacrylate, and vinyl acetate. In addition to these species, many copolymers have been prepared from oligomers of PCL. In particular, a variety of polyester-urethanes have been synthesized from hydroxy-terminated PCL, some of which have achieved commercial status (9). Graft copolymers with acrylic acid, acrylonitrile, and styrene have been prepared using PCL as the backbone polymer (60).

In a related study, the group of Bazureau applied their polyethylene glycol-grafted ionic liquid phases (ILPs) to the preparation of 2-thioxotetrahydropyrimidinones [105], After the initial formation of acrylate-bound ILPs utilizing acryloyl chloride in refluxing dichloromethane, several primary amines were attached in a Michael addi-... 

Antipina et al. (1972) also investigated the complexation of polyethylene glycols) with linear polymethacrylic and acrylic acids of molecular... 

An efficient one-pot synthesis of isoxazolines, using soluble polymer-supported acrylate has been described (174). Thus, the addition of 1,4-benzenedicarbonitrile N,N -dioxide (generated from N, N -dihydroxy-1,4-benzenedicarboximidoy 1 dichloride) to polyethylene glycol-supported 2-propenoic acid 2-hydroxyethyl ester 32 (P = polyethylene glycol support) followed by cleavage of the bond with the support gave 3,3/-(l,4-phenylene)bis[4,5-dihydro-5-isoxazolecarboxylic acid] di-Me ester (33) in 97% yield. 

The bioadhesive characteristics of tablets for oral use made from modified starch, poly(acrylic acid), polyethylene glycol) and sodium carboxymethyl cellulose were recently investigated [406]. In this work, the force and energy adhesion were determined in vitro, and maximum adhesion times were evaluated in vivo in humans [406], In the in vitro, studies, the poly(acrylic add) gave the best performance, however in vivo bioadhesion was not strongly correletated with... 

Other hydrogels are prepared from poly(a-hydroxylic) acids, e.g., lactic acid, polyacrylic acid, acrylamides and acrylated polyvinyl alcohol, and polyethylene glycol. 

Allyl methacrylate and allyl acrylate are difunctional monomers, triallyl phosphate is a trifunctional monomer, and polyethylene glycol dimethacrylate is a polyfunctional monomer. All these lead to cross-linked graft copolymers. 

All but the polyurethane are characterized by methylene backbones with ligands that are sufficiently polar to make them water soluble. Thus, upon dissolution in water, the polarity of the water molecule associates with the polarity of the acrylic or acrylamide groups to form a shell. We discussed hydrophilic polyurethanes that are typically cross-linked and are not (but could be) considered effective thickeners. Nevertheless they too have hydration shells developed due to the influence of the polyethylene glycol backbone. The extent of that shell is determined by the hydro-philicity of the ligand the acrylic > acrylamide > alcohol > polyurethane. The volume...

Bradley described the first solid-phase synthesis of PAMAM dendrimers in 1997 [220]. To this end, phthaloyl-protected norspermidine was coupled to aminomethyl functionalised polystyrene-polyethylene-glycol resin ((PS-PEG)-NH2) through an acid-labile linker (see Fig. 23). PAMAM dendrons were assembled by treating deprotected scaffold-bound resin 24 first with an excess of methyl acrylate...

Similarly, Chien et al. used a poly(acrylic acid)/poly(acrylamide) (PAA/PAM) multilayer system in which PAA was replaced by PAA conjugated with photoreactive 4-azidoaniline (AZ) after several bilayers [110]. As a result, the polyelectrolyte multilayer could be covalently crosslinked by UV irradiation through a mask. For an enhanced cell repellence, poly(allylamine) was conjugated with polyethylene glycol methyl ether) and incorporated into the top layers of the film.
