Mechanism of Bulk Copolymerization of Styrene and Maleic Anhydride

Abstract

Abstract: Because the interaction between the carbonyl groups of maleic anhydride (Man)and benzene ring of styrene(St) was the major part in the charge transfer complex (CTC)formed by St and Man, The unsaturated carbon--carbon double bond of Man was not in aadvantageous position in copolymerization with the ethyl group of St.The calculated data fromthe Complex-Dissociation Model were coincided well with experimental ones.It is reasonableconsidered that the bulk copolymerization of St and Man proceeded according to theComplex--Dissociation Model.The fitting data also showed that the probability of alternativecopolymerization increased with the increasing of temperature among 70～140℃.

Key words: Alternative copolymerization, Complex-Dissociation Model, Complex-Participation Model
