摘要
通过用静、动态激光散射技术测定并讨论分子量（）随反应时间变化的定量关系式，并用分子尺寸（Ｒ＿ｇ、Ｒ＿ｈ）随反应的变化趋势，δ＝Ｒ＿ｇＲ＿ｈ随反应的指数变化规律及支化、多分散性对δ的影响来研究苯乙烯－二乙烯苯自由基交联共聚反应中支化大分子链的增长行为。
The propagation behavior of chain branched during radical crosslinking copolymerization was monitored by means of both static and dynamic laser light scattering.The relationship on(1-Was discussed,here r=1.94.In the meantime,the evolution of molecular size(Rg,Rh)was detected.The exponential property of δ=Rg/Rh with time was investigated. The influence of branching and polydispersity on δ also was studied.
