摘　　要：阴离子聚合是高分子化学教学中的重要内容,正确理解阴离子聚合的有关概念,掌握利用活性阴离子聚合的机理特征处理阴离子聚合动力学,对阴离子聚合的学习十分有益。本文针对阴离子聚合中烯类单体结构特点、阴离子引发剂与单体匹配本质、活性阴离子聚合动力学中聚合速率、聚合度及聚合度分布等重难点内容作了较深入的分析,其中利用单体成键概率p及总成键概率P对活性阴离子聚合的聚合度及聚合度分布作了重点推导分析。The anionic polymerization is very important in studying the course of polymer chemistry. The correct understanding the involved concepts of anionic polymerization, mastering living anionic polymerization mechanism dealing with anionic polymerization kinetics is of very importance for leaning anionic polymerization. In this presentation, the structural features of vinyl monomers, the essence of initiator initiating vinyl monomer, the polymerization rate, polymerization degree and distribution of polymerization degree were discussed carefully. According to the characteristics of the anionic polymerization mechanism, the monomer bond probability p and the total bond probability P are used to derive and analyze the polymerization degree and polymerization degree distribution of living anionic polymerization.
