Abstract: The molecular weight theory and calculation equation of copolymer were set up after consideration with the influence of composition and sequence distribution. The molecular weight for St/PMIcopolymer was investigated by means of GPCconnected with DRand UVdetectors. From the mechanism of St/PMIcopolymerization, a model of molecular weight for St-PMIcopolymer was proposed to predicate the effects of initiator concentration, feed fraction and conversion on the molecular weight of St-PMIcopolymer. The predicted results coincided with the experimental data.
