摘　　要：使用可逆碘转移聚合（RITP）的方法,以I2作为链转移剂,合成了第一段为甲基丙烯酸2,2,2-三氟乙酯（TFEMA）,第二段为甲基丙烯酸羟乙酯（HEMA）的两亲性嵌段共聚物TFEMA-b-HEMA,并对聚合物进行了FT-IR、1H NMR、GPC的表征。结果表明成功合成嵌段共聚物,并且分子量分散系数在1.4~1.6之间,达到活性聚合的效果。In this work,it has been demonstrated that reverse iodine transfer polymerization（ RITP） with I2 as chain transfer agent（ CTA） of fluorinated amphiphilic block copolymers poly（ TFEMA）- b- poly（ HEMA）（ where TFEMA and HEMA stand for 2,2,2- trifluoroethyl methacrylate,Hydroxyethyl methacrylate,respectively） were successfully applied to solution polymerization. and characterized by means of FT- IR,1H NMR,GPC. The results indicated that fluorinated amphiphilic block copolymers has been successfully synthesized and has a clear structure with controllable molecular weight and narrow distribution.
