Abstract:

This paper summarizes technologies of chlorinated polypropylene（CPP）production，and presents several new technologies for CPP production that do not use carbon tetrachloride（CTC）. The feasibility and applicability of different technologies for CPP production are analyzed. Non-CTC solvent technology is the optimum process to produce CPP with low chlorinity which could be used for printing ink production. Water phase suspension technology is suitable for preparing CPP  for applied materials production. Despite its advantage of energy-saving and emission-reduction，solid-phase technology is still not mature and should be further improved. Finally，it is suggested that new varieties of CPP should be developed to meet the increasing demands of diversified production.

摘要：

综述了氯化聚丙烯（CPP）的主要生产工艺，提出了几种不使用四氯化碳（CTC）的CPP生产新工艺。分析了不同生产工艺的可行性和适用性，得出非CTC溶剂法是生产油墨用途的低氯化度CPP的最佳选择，而水相悬浮法适用于生产材料等用途的CPP产品，固相法虽有节能减排的特点但还不成熟，值得深入研究的结论。建议大力开发CPP新品种，满足日益多样化的产品需求。
