摘　　要：介绍了高分子物理与高分子化学中与分子量调节剂有关的几个概念,包括链转移剂、分子量稳定剂、粘度稳定剂以及封端剂等,分别论述了在加聚反应和缩聚反应中,它们与分子量调节剂的关系、异同以及在高分子化学和物理中的作用。其中,在加聚反应中分子量调节剂与链转移剂是相同的概念,而在缩聚反应中与分子量调节剂相关的概念则比较多,没有统一的定义,由于分子量与粘度的关系密切,因此经常被称为粘度稳定剂。最终,指出在高分子化学与高分子物理课程讲授中综合运用两方面的知识的重要性。Several concepts concerned with molecular weight regulator were introduced, including chain-transfer agent, molecular weight stabilizer, viscosity stabilizer and end capping agent. Their connections, similarities and differences with molecular weight regulator and applications were summarized detailly in the addition polymerization and condensation polymerization. In the addition polymerization, the molecular weight regulator and chain-transfer agent are the same concept. Whileas in the condensation polymerization, there are several concepts concerned with with molecular weight regulator. There is no uniform definition. It was always called viscosity stabilizer because the relationship between the molecular weight and viscosity is very intimate. And it was pointed out that synthetically using the knowledge of polymer physics and polymer chemistry was very important when teaching the polymer physics or polymer chemistry
