摘要: 研究了单体配比、引发剂浓度、聚合温度、转化率等因素对偏二氯乙烯(VDC)-丙烯腈(AN)悬浮共聚树脂的组成、相对分子质量和聚合速率的影响,建立了动力学模型,讨论了AN的水溶性对树脂组成的影响,提出了相对分子质量与聚合温度及引发剂浓度关系的模型。

Abstract: The effects of monomer ratio, initiator concentration, polymerization temperature and conversion on the composition and molecular weight of vinylidene chloride(VDC) - acrylonitrile(AN) copoly-mer, and rate of reaction were studied. A kinetic rate model of suspension copolymerization is suggested. The dependency of copolymer composition on AN concentration in the water phase was discussed. A model of molecular weight as a function of polymerization temperature and initiator concentration was proposed.
