✦ Synopsis

The ternary copolymerizations of glycidyl(methyl) methacrylates (GMA and MMA), styrene (St), and maleic anhydride (MA), considered as acceptor(A 1 )donor-acceptor(A 2 ) systems, were carried out in methyl ethyl ketone in the presence of benzoyl peroxide as initiator at 50 -80°C. Constants of copolymerization, complex formation, and some kinetic parameters for the monomer systems studied were determined by the methods of Hanna-Ashbaugh, Kelen-Tu ¨do ¨s, and Seiner-Litt, as well as by dilatometry, respectively. The results show that terpolymerizations were carried out through primary "complex" mechanisms at near-binary copolymerization of GMA (or MMA) with the St . . . MA complex. The terpolymers synthesized which comprised free anhydride and epoxide reactive groups easily underwent crosslinking by thermotreatment and by UV irradiation, which was confirmed by DTA, TMA, and FTIR analyses.
