Abstract: The composition change of vinyl monomer/N-phenylmaleimide (PMI) copolymer with conversion was predicted with stepwise calculation method of Mayo-Lew is equation. The composition of copolymer could be controlled and optimized by properly selecting the comonomer and the feed fraction. Based on the characteristics and technology of vinyl chloride/PMI/acrylonitrile copolymerization, the optimum range of monomer feed fraction was obtained.
