摘要
利用1H NMR,13C NMR方法,对2种工业级聚苯乙烯(EPS、HIPS)谱图进行了分析,找出了它们的特征信息;并对2样品进行了热老化模拟实验,得到了样品热老化时间与化学结构组成之间的变化规律。
Two kinds of industrial PS products （EPS,HIPS） were analyzed by using 1H, 13C NMR methods and their characteristic spectra were identified. The two products were then thermally degraded at different times followed by NMR analysis again to find out the relationship between heating aging time and the structural changes.
