Polymethacrylate copolymer
WebAs shown by the copolymerization diagrams and the copolymerization parameters, the copolymerization of 4-(4-methacryloyloxyphenyl)butan-2-one with n-butyl methacrylate is a nearly ideal copolymerization using short polymerization time (20 min). Extending the polymerization time results in slight deviation from an ideal copolymerization. WebAnionic polymers: Anionic polymethacrylate polymers contain methacrylic acid functional groups, which dissociate and render the polymer soluble at the higher pH of the small …
