摘要(Abstract):

以离子液体1-丁基-3-甲基咪唑硼酸盐([BMIM]BF4)为溶剂,研究了丙烯腈、甲基丙烯酸甲酯和衣康酸在离子液体中的自由基共聚反应。研究结果表明:衣康酸对共聚物的相对分子质量影响很大;离子液体中的共聚产物的化学结构与常规NaSCN水溶液中的聚合产物的结构基本相同,但立构规整性略低。
Free radical copolymerization of acrylonitrile (AN), methyl methacrylate (MMA) and itaconic acid (IA) was carried out in synthesized ionic liquid, 1-butyl-3-methylimidazolium BF4,using AIBN as initiator. The resalt showed that IA had a big effects on molecular weight of copolymer. Especially, the effects of ionic liquid on chemical structure of product in ionic liguid were similar with that of product in NaSCN sulotion, but the tacticity was lower.
