两亲性丙烯酸酯共聚物的聚合研究

Studies on Copolymerization of Amphiphilic Acrylate

利用过氧化苯甲酰为引发剂探讨了甲基丙烯酸β－羟乙酯和丙烯酸长链烷基酯的自由基共聚合。重点讨论了合成条件如溶剂、沉淀剂、引发剂用量、单体配比、反应时间等对共聚反应的影响以及各种聚合条件对该共聚物的组成、结构和性能的影响。并用ＩＲ，ＧＰＣ，１３ＣＮＭＲ等手段对共聚物进行了表征。

The radical copolymerization of 2 hydroxyethyl methacrylate(HEMA) and aliphatic acrylate has been carried out in dioxane at 80℃ using benzoyl peroxide as initiator. The study emphasized on the relationships between the composition and structure of copolymers and the polymerization conditions. The effect of solvents, precipitating agents, the amount of initiator, mole ratio of monomers and reaction time on the polymerization reaction was investigated. The copolymers were characterized by IR, GPC and 13 C NMR.
