摘要
本文用红外光谱分析了聚氯乙烯(PVC)和氯化聚氯乙烯(CPVC)的分子结构,用电导法评价了它们的热稳定性. 试料 PVC系天津化工厂生产,XS-7型;CPVC系前者的氯化产品,由安徽化工研究所提供,含氯量64％,日本产CPVC,牌号H827,含氯量68.5％.
The thermal stabilities of chlorinated polyvinylchloride(CPVC) and polyvinyl chloride(PVC) were compared through their infrared spectra and conductivity data. CPVC showeda much higher thermalstability than PVC. The influence of chlorine content in polymers onthe stability. has been discussed.
