摘要
介绍了水相悬浮法CPVC生产新工艺：分段控制温度（45～55℃，65～75℃，80～85℃），分次加入复合引发剂，并用有机碱稀溶液进行稳定化处理，可以得到氯含量高、氯化均匀、热稳定性良好、色泽理想的CPVC。
A new process for the production of CPVC by aqueous suspension method was intro- duced, in which, the reaction temperature was controlled step by step （ 45 - 55℃, 65 - 75℃, 80-85 ℃）, the complex stabilizer was added in batches, and diluent organic alkaline solutions were used to stabilization treatment, and thus CPVC resins with high chlorine contents, well distributed chlorine atoms, good heat stability and ideal color were obtained.
