Radical copolymerization of donor-acceptor monomers, i.e., allylglycidyl ether (AGE), maleic anhydride (MA) and methyl methacrylate (MMA) are studied, where binary copolymerization of AGE...MA complex with MMA is obtained. Constants of charge transfer complex formation (K-c) and copolymerization (r(1) and r(2)) are determined by H-1-NMR and Kelen-Tudos methods, respectively. It is found that synthesized film-forming terpolymers with free epoxy and anhydride groups on side chain of macromolecules are being crosslinked easily under the effect of temperature and/or UV-irradiation. Observed crosslinking effect is proved by the DTA, TGA, and IR spectroscopic analyses. It is shown that complex-radical terpolymerization is very convenient method for the designing of reactive functional macromolecules of linear structure with self-crosslinking properties which can serve as a basis for the use in photolithographic applications.
