自由基聚合动力学的学习探讨

Discussion on the Kinetics of Free Radical Polymerization

掌握自由基聚合动力学的内容,对自由基聚合度的学习十分有益。论文探讨了自由基聚合反应中动力学链长及自由基链终止方式对聚合度的影响关系,利用动力学链长概念及自由基链转移生成聚合物分子的观念得到了有链转移反应时的聚合度与动力学链长的计算公式,并阐明了其物理意义。

The content of free radical polymerization kinetic is very important in the study and teaching of radical polymerization.In this paper,the concept of kinetic chain length and radical chain termination method that affects the degree of polymerization are discussed carefully.Expressions of degree of polymerization including kinetic chain length in the presence of the chain transfer are obtained,and illustrate its physical meaning.
