摘　　要：根据武汉石油化工厂生产实际及相关试验，讨论小本体聚丙烯应用络合二型及CS-1型催化剂出现的产品质量问题、对粘料、结晶料、产品灰分含量及氯含量高、同批粉料熔融指数（MI）不同、小黑点料等质量问题的形成原因进行分析，认为原料质量、反应时间、冲催化剂时釜内活化剂浓度、升温时间、催化剂及活化剂量、回收包装温度、轴封状况对上述质量问题存在显著影响。The product quality problems arisen from using type Ⅱ complex catalyst and CS-1catalyst in bulk polymerization unit in Wuhan Petrochemical Works are discussed. It is considered that feed quality, reaction time, co-catalyst concentration during adding catalyst, heating rate, catalyst and cocatalyst usage, recovery and packing temperature and axle sealing have significant influence on the product quality through a detailed analysis of stickiness and crystalline of ,polypropylene, product ash content and chlorine content, different melting index for polypropylene powder of same batch and small black particles, etc.
