Abstract: The effects of reaction temperature, initiator concentration, and molar fraction of monomer on the copolymerization kinetics of styrene/N-phenylmaleimide were studied in detail. The copolymerizations of styrene, methyl methacrylate, acrylonitrile, or their mixtures with N-phenylmaleimide, N-cyclohexylmaleimide, or N-(o-chlorophenyl)maleimide were also investigated and discussed with the structure of comonomer pairs.

Key words: Vinyl monomer, N-Substituted maleimide, Kinetics of copolymerization
