摘要

从作者提出的统计/动力学建模思想出发，建立了基链在溶胶/凝胶间分配模型，进而建立了溶胶分子平均聚合度模型．仿真计算表明：凝胶分中基链链长明显大于溶胶分；凝胶点过后，溶胶分子量急剧下降，随后根据竞聚率的不同，有不同的变化趋势．模型应用于氯乙烯／邻苯二甲酸二烯丙基酯悬浮交联聚合体系，可较好地预测溶胶分子量随聚合过程的变化．

Abstract

Based on the statistical/kinetic method previously presented by the authors

a partition model of primary chains between sol and gel is developed.A model of average molecular weight of the sol is also proposed.From computer simulation

it is found that the chain length in the gel is much bigger than that in the sol and once passing gel point

the molecular weight decreases sharply

depending on reactivity ratio.The present model is successfully applied to predict the development of molecular the weight of sol in the vinyl chloride/diallyl phthalate suspension crosslinking copolymerization.
