Polymerization of methyl methacrylate photosensitized by the systems derived from isobutyl ester of p-benzophenonecarboxylic acid and dimethylaminoethyl methacrylate-methyl methacrylate copolymer

Copolymers with tertiary amino side groups were synthesized by thermal copolymerization of MMA with dimethylaminoethyl methacrylate. Photosensitized MMA polymerization was carried out in the presence of donor-acceptor systems with a variable ratio of the acceptor (isobutyl ester of p-carboxylic acid) and donor (dimethylaminoethyl methacrylate-methyl methacrylate copolymer). A suggestion is made about the possible structures of photocopolymers and about the chemical process of their formation depending on the content of dimethylaminoethyl methacrylate-methyl methacrylate copolymer in the donor-acceptor system.
