摘要

苯乙烯与一缩二乙二醇二甲基丙烯酸酯进行本体和不同溶剂中的交联共聚。研究了动力学、凝交化和相分离性质。测得两种单体的竞聚率(60℃)分别为0.54和1.85。测得凝胶化时间及转化率及交联剂浓度的关系。并研究了交联剂和溶剂对反应过程和产物结构的影响。还对一些实验事实用微凝胶理论作了解释。

Abstract

The crosslink copolymerization of styrene (S) and diethylene glycol dimethac-rylate (DEGDM) was carried out in and without the presence of diluents

and the kinetics

phase separation and gelation were investigated. The reactivity ratios (60℃) were found to be y(DEGDM)=1.85 and y(S)=0.54. The dependence of both time and conversion at the onset of gelation on concentration of DEGDM were obtained. And the effect of properties of the reaction and product on crosslinker and diluents were examined systematically. Some experimental results were explained with microgel formation theory.
