In spite of this, the preparation of thiol-end functionalized PMMA was achieved by introducing a short block of polystyrene after the RAFT polymerization of MMA.Third, RAFT technique was applied to design and synthesize some well-defined poymers. Five monomers, lauryl methacrylate,(N,N-dimethylamino)ethyl methacrylate, poly methyl ether methacrylate, 4-(4\'-cyanobiphenyl-4-yloxy) butyl methacrylate and 2-ethyl methacrylate were chosen to RAFT homopolymerization or copolymerizations mediated by cumyl dithiobenzoate.

RAFT方法在具有特定结构聚合物的设计与合成上的应用，在机理研究的基础上，本论文选择五种不同结构的甲基丙烯酸酯类单体：lauryl methacrylate，(N，N-dimethylamino)ethyl methacrylate，polymethyl ether methacrylate，4-(4'-cyanobiphenyl-4-yloxy)butyl methacrylate和2-ethyl methacrylate，用CDB调控RAFT聚合的方法设计合成了一些特定结构的聚合物，详细而深入地研究了它们的均聚、共聚动力学，发现了双硫酯并非在聚合反应初期就全部转化，而是随着反应进行逐步消耗，这与理想的活性聚合体系有很大差别。
