MECHANISM OF BULK COPOLYMERIZATION OF STY RENE AND MALEIC-ANHYDRIDE

Because the interaction between the carbonyl groups of maleic anhydrid e(Man) and benzene ring of styrene(St) was the major part in the charg e transfer complex (CTC) formed by St and Man, The unsaturated carbon- carbon double bond of Man was not in a advantageous position in copoly merization with the ethyl group of St. The calculated data from the Co mplex-Dissociation Model were coincided well with experimental ones, I t is reasonable considered that the bulk copolymerization of St and Ma n proceeded according to the Complex-Dissociation Model. The fitting d ata also showed that the probability of alternative copolymerization i ncreased with the increasing of temperature among 70 similar to 140 de grees C.
