三元多嵌段共聚物分子链结构的统计表征

Statistical Characterization on the Molecular Chain Structure of Ternary Multi-Block Copolymers

本文根据三元多嵌段共聚反应的一般模型,运用母函数方法,严格推导出了型三元多嵌段共聚物的分子量分布及平均分子量的解析表达式.对几种具有特殊分布的预聚体进行了讨论.

In this paper, by using the generating function method, the expressions of the average molecular weight and the molecular weight distributions of ternary multi- block copolymers of type are derived, giving a theoretical method for characterizating the molecular structure of this block copolymer. The properties of some block copolymers composed of the prepoly-mers with a special molecular weight distribution are discussed.
