摘要
以偶氨二异丁腈（AIBN）为引发剂，采用溶液一沉淀聚合方法制得了苯乙烯－马来酸酐共聚物（SMA），并对所合成的共聚物的共聚组成、共聚结构及热性能进行了分析．实验结果表明：苯乙烯－马来酸酐共聚体系存在前末端效应，共聚反应不是严格的交替共聚，而是交替倾向很大的无规共聚反应；聚合体系的溶剂对反应的前末端效应影响较大．
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.
