摘要： 聚苯乙烯是一种耐辐照的通用高分子材料。用其它方法来表征其微观反应参量,辐照剂量需要很大,周期长,而用SEC-LALLS法,则仅需凝胶点前知识,相应需要时间短,有关这方面的研究工作还未见文献详细报导。

Abstract: The sol of γ-irradiated polystyrene has been investigated by using SEC-LALLScombination technology. The changes of the sol properties after and before gel point forpolystyrene were observed. The results show that in the early stage of irradiation mainlythe molecules of higher mloecular weight take part in crosslinking reaction. The concentration of low moleculat weight fractions Changes little before the gel point,but it changesgreatly near and after the gel point.
Key words: polystyrene, sol property, high energy irradiation, molecular weight distribution
