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

Shirota's kinetic model and our kinetic model were used to treat thekinetic data of styrene (St) and N-phenylmaleimide (PMI)copolymerization in which charge-transfer complex (CTC) was formed.The results obtained by Shirota's kinetic model were disagreed withthe experiments and the experimental phenomena could not be explained.The kinetic data of all feed fractions can be treated with our kineticmodel, and the experimental phenomena can be explained from thepropagation constants and reactivityratios. Our kinetic model is also suitable for the kinetic dataof methyl methacrylate(MMA) and PMI copolymerization in which CTC can not be formed.
