Polyethyleneglycol dimethacrylate

The base methacrylate monomers utilized were a polyethyleneglycol dimethacrylate (PEGMA - produced by Loctite), an ethoxylated bisphenol—A dimethacrylate (EBIPMA - produced by AKZO), a urethane methacrylated capped poly(butadiene acrylonitrile) polyol, and hydroxy-propyl methacrylate (HPMA - Rohm and Haas). The following maleimide capped monomer/prepolymers were examined N-phenyl maleimide (NPM), meta-phenylene dimaleimide (m-PDM), and a reaction product of methylenedi-aniline and excess methylenedianiline bismaleimide (P-MDA-2MDABM), sold by Rhodia Corp. under the tradename of Keramide... 

Covalently crosslinked IPN were realized by combination of polymerization and polyaddition reactions. Generally, such IPN are prepared in the order polyaddition first and polymerization reaction second. The other sequence was demonstrated in IPN from polyethyleneglycol dimethacrylate blended with star-shaped poly[(rac-lactide)-cc>-glycolide], which was first photopolymerized and afterwards the polyesterurethane network was formed using isophorone diisocyanate [38]. While R and were reported to be above 93%, TJrans = Tg could be adjusted between -23 and 63 °C.

Also in the field of hydrogels, (meth)acrylates play an important role. Since there is quite a number of hydrophilic methacrylate-based monomers available, radical copolymerization with an appropriate crosslinking monomer leads to network formation. The most widely used monomers are 2-hydroxyethyl methacrylate HEMA, 2-aminoethyl methacrylate and the alkyl derivatives, amethacrylamid and the alkyl derivatives, ethyleneglycol dimethacrylate EGDMA, and polyethyleneglycol dimethacrylate PEGDMA.
