摘　　要：以甲基丙烯酸三氟乙酯、丙烯酸丁酯、甲基丙烯酸甲酯、甲基丙烯酸缩水甘油酯和苯乙烯为基本原料,用半连续滴加的方法制备了共聚物乳液。FT-IR证明了所用单体甲基丙烯酸三氟乙酯参与了共聚反应。讨论了氟单体用量对转化率的影响。讨论了乳胶膜的吸水率的影响因素。The title copolymer emulsion is prepared by use of a semi - continuous drop - feeding process method based on trifluoroethyl methacrylate, butyl methmacrylate, methyl methacrylate and styrene as raw materials and GMA as crosslinker. FTIR test indicates that the semi -continous drop -feeding process can prepare low surface energy copolymer emulsion with shell layer containing fluorine. And it is proved that the trifluoro ethyl methacrylate takes part in the copolymerization reaction. The influence of fluoro monomer amount on conversion ratio and influencing factors on water absorption ratio of latex film are discussed.
