摘要
研究了使用DMC催化剂制备环氧丙烷聚醚时 ,聚合温度、催化剂浓度、加料速度对聚醚相对分子质量和相对分子质量分布的影响规律。采用连续加起始剂的操作方式可窄化聚醚的相对分子质量分布 。
The effects of temperature,concentration of catalyst and feeding rates of monomer on molecular weight and molecular weight distribution in polymerization of propylene oxide with DMC catalyst were discussed.Adding starter continuously can make molecular weight distribution narrow.Adjusting acid number of starter can reduce polymerization induction time.
