Kinetic treatment for copolymerization of styrene or methyl methacrylate with N-phenylmaleimide

Shirota's kinetic model and our kinetic model were used to treat the kineti c data of styrene (St) and N-phenylmaleimide (PMI) copolymerization in whic h charge-transfer complex (CTC) was formed. The results obtained by Shirota 's kinetic model were disagreed with the experiments and the experimental p henomena could not be explained. The kinetic data of all feed fractions can be treated with our kinetic model, and the experimental phenomena can be e xplained from the propagation constants and reactivity ratios. Our kinetic model is also suitable for the kinetic data of methyl methacrylate (MMA) an d PMI copolymerization in which CTC can not be formed.
