摘　　要：氯化聚乙烯橡胶(CM)的三段水相悬浮法合成工艺是在水相悬浮体系中对高密度聚乙烯(HDPE)进行低温、中温、高温3个温度段氯化而制备CM。该法对设备材质要求低、生产过程易控制、产品质量稳定、生产效率高;氯化反应均匀,产品几乎无HDPE残留结晶;通过原料选择,控制低温、中温、高温3个氯化温度段的氯气通入量以及最高氯化温度,可以制备门尼粘度和强度性能不同的CM,满足客户的特定需求。This paper introduces a new three stage aqueous suspension process of chlorinated polyethylene rubber（CM）,which is made from high-density polyethylene（HDPE） through the three temperature stages chlorination reaction. In this process regular equipment and raw materials are used,production process is easily controlled,product quality is stable and production efficiency is high. The chlorination reaction is uniform and the product shows no residual HDPE crystallinity and possesses good elasticity. Customized products with required Mooney viscosity are easily produced by selection of raw materials,control of chlorine amount during the three temperature stages and maximum chlorination temperature.
