摘　　要：活性阴离子聚合为聚合物分子设计和合成提供了一种有效方法。以1,1二苯基己基锂(DPHLi)为引发剂,添加LiClO4络合剂,采用活性阴离子聚合体系制备了单分散聚甲基丙烯酸乙酯(PEMA)。考察了聚合温度、引发剂、添加剂等工艺参数对聚合反应的影响规律,并研究了不同pH值聚甲基丙烯酸乙酯的降解性能。Living anionic polymerization provides an efficient method for polymer chain architecture. It was showed that polymerization of ethyl methacrylate with DPHLi as an initiator in the presence of LiC104 led to living anionic polymeri zation and the polymer with relatively narrow molecular weight distribution. We studied the influence of the polymerization temperature, inititator structure and additives on living anionic polymerization. The degradation property of monodisperse poly（ethyl methacrylate） in different pH solution were investigated.
