摘　　要：利用差示扫描量热仪研究了氯化程度对氯化聚乙烯玻璃化转变温度的影响。结果表明:熔融热和氯含量是影响氯化聚乙烯玻璃化转变温度的重要因素,熔融热提高,玻璃化转变温度上升;氯含量增加,玻璃化转变温度上升;玻璃化转变温度上升,氯化聚乙烯的低温性能下降。The influences of chlorination degree on the glass transition temperature of chlorina- ted polycthylenc wcrc studied by DSC. The results showed that mclting heat and chlorine contents were the key factors of influencing the glass transition temperature of chlorinated polyethylene, thc glass transition temperature increased with the increase of melting heat and chlorine contcnts, and the low temperature performance of chlorinated polyethylene degraded with the increase of its glass transition tcmpcraturc.

关 键 词：氯化聚乙烯 玻璃化转变温度 熔融热 氯含量
