摘要

研究探讨了己内酰胺和八甲基环四硅氧烷两种完全不同的环单体的共聚过程。在反应初期

环硅氧烷快于己内酰胺而先聚合

随后己内酰胺很快达高转化率。随聚合反应时间延长和环硅氧烷单体配比的增加

共聚体中的硅氧烷含量都相应增加。研究提出并证实了聚合过程中的一些主要反应

并由此推断了共聚产物的结构表达式。

Abstract

The process of copolymerization of caprolactam (CL) with octamethyl cyclotetrasiloxane (D4) has been investigated. In the course of polymerization of CL and D4

D4 polymerized rapidly at first

then CL continued to polymerize and attained the high conversion of above 85%. The content of siloxane component in the copolymer chain extended with the reaction time and with increase of the monomer ratio of D4. The main reactions in the polymerizing process was proposed and the structure of copolymer was suggested.
