摘　　要：介绍了氯化聚氯乙烯树脂的几种生产方法 ,着重研究了利用热引发水相悬浮法生产CPVC的生产工艺。试验结果表明 :反应时的温度、压力、引发剂添加量及后处理条件对PVC的氯化均有影响 ,因此氯化反应温度最好控制在 80～ 14 0℃ ,压力控制在 0 .1～ 0 .5MPa ,引发剂添加量在 0 .0 1%～ 0 .3%。In this paper some methods of production of chlorinated PVC resins are introduced,among which thermal initiation-aqueous suspension process is studied emphatically.The results of experiments showed that because reaction temperature,pressure,addition amount of initiators and conditions of post-treatment could all influence chlorination of PVC,the chlorination temperature,presure and amount of initiators should be controlled within the range of 80～140 ℃, 0.1～ 1.5 MPa,and 0.01%～0.3% respectively.
