摘要

用Brillouin散射研究了聚苯乙烯的动态力学性质和弛豫过程及交联对它们的影响。除了观察到它们的高温(T>Tg)无定形弛豫外

还在交联的聚苯乙烯中发现了一种新的弛豫过程

研究了不同交联结构对这种弛豫过程的影响

求得其活化能为12kcal/mol左右。分析了它们所关联的分子运动机制。

Abstract

The Brillouin scattering was used to investigate the effect of crosslinking on the dynamic mechanical properties and the relaxations of polystyrene. It was found that there is a new relaxation in the cross-linked polystyrene besides the high temperature (T>Tg) amorphous relaxation. The effect of crosslinking on this relaxation was examined. The activation energy of this relaxation was determined to be about 12 kcal/mol. The molecular origins of this relaxation were proposed.
