Styrene-Maleic Anhydride Copolymer was prepared through solutionprecipitation polymerization with initiator AIBN. The structure and properties ofcopolymer were determined by 13C NMR,DTA and chemical analysis. The result shows:The Styrene-Maleic Anhydride copolymerization is not strict alternating copolymerization.It's random copolymerization which with high tendence of alternation effect. Thecopolymer with low Maleic anhydride ( 15 %mol) has much more application in materialindustry.
