摘要
用热分析法对硫磺法合成的高粘度聚苯硫醚（ＰＰＳ）的结晶行为和热裂解行为进行了初步探讨，并与硫化钠法ＰＰＳ进行了对比。结果表明：杂质的存在对硫磺法ＰＰＳ的交联结构，热稳定性和结晶行为都有不同程度的影响。
This paper reports preliminary results of the crystallization and the thermal degradationbChavior of high viscosity polypbenylene sulfide ( PPS ) of the sulfur method by thermoanalysis.The results are compared with PPS of the Na_2S method,showing that the crosslinking structure,the thermal stability and the crystalline behavior of PPS of the sulfur method are affected by theimpurity.
