摘　　要：基于两性离子单体甲基丙烯酸羧酸甜菜碱(CBMA)的结构特征,设计了不同结构和特性的单体进行共聚反应及相关结果分析,在本部分工作中,我们首次将两性离子单体与甲基丙烯酸五氟苯酯(PFMA)等具有可替换性或响应性的单体进行可逆加成裂解链转移自由基聚合(RAFT)反应,通过对反应条件的摸索和聚合物结构的分析发现,对于两性离子而言,RAFT聚合不能实现两性离子的高效共聚,但是为之后的两性离子聚合物的合成提供了新思路。Based on the structural characteristics of the zwitterionic monomer methacrylic acid carboxybetaine(CBMA),the synthesis of copolymers with different structures and characteristics was designed and the related results were analyzed.In this part of the work,the CBMA RAFT reaction is carried out on monomers with the alternative or responsiveness such as pentafluorophenyl methacrylate(PFMA).It is found that the RAFT polymerization could not achieve the high-efficiency copolymerization of zwitterions by analyzing the reaction conditions and polymer structures.However,it provides a new idea for the synthesis of the later zwitterionic polymers.
