✦ Synopsis

Three types of novel N-[4-(NЈ-substituted aminocarbonyl)phenyl] maleimide (RPhMI: N-substituent (R) ϭ phenyl, cyclohexyl, and cyclododecyl) were synthesized and homopolymerized under several conditions. In the copolymerizations of RPhMI (M 1 ) with styrene (ST; M 2 ) or methyl methacrylate (MMA; M 2 ), monomer reactivity ratios and Alfrey-Price Q, e values were determined. All homopolymers decomposed without softening and melting points. The initial degradation temperatures (T d ) of poly(RPhMI)s were over 320°C. The glass transition temperatures (T g ) of RPhMI copolymers were much higher than those of N-phenylmaleimide (PhMI)-ST, PhMI-MMA, N-cyclohexylmaleimide (CHMI)-ST, and CHMI-MMA copolymers. Thermal stability of the terpolymers of RPhMI with ST and acrylonitrile (AN) was higher than that of ST-AN copolymers, i.e., AS resin.
