Various mole ratios of acrylonitrile and methyl methacrylate were used to copolymerize in aqueous solution by Redox and the copolymers were obtained. The copolymers containing MOCT were synthesized by adding MOCT before copolymerization. The copolymer were derived from the copolymerization of AN and MMA in 30L kettle and then were mixed with various contents of MOCT, the copolymer films were cast by solution of the copolymer containing MOCT.

本课题采用不同摩尔比的丙烯腈和甲基丙烯酸甲酯进行水相沉淀聚合，制备了AN／MMA共聚物；在聚合阶段加入正十八烷微胶囊，制得了正十八烷微胶囊含量不同的共聚物；选择合适的条件进行大釜聚合，得到共聚物后与不同比例的正十八烷微胶囊混合，通过流延制得正十八烷微胶囊含量不同的共聚物膜；并尝试进行了纺丝实验。
