本文着重讨论了相转移催化剂聚乙二醇和四丁基溴化铵在三种类型的溶剂中的催化作用。研究了不同分子量的聚乙二醇和它的用量及不同结构的季胺盐对最终聚合物的比浓粘度的影响。
This article focuses on the catalysis of phase transfer catalysts, polyethylene glycol and tetrabutylammonium bromide, in three types of solvents. The effect of polyethylene glycol with different molecular weight and its amount and quaternary ammonium salts of different structures on the reduced viscosity of the final polymer was investigated.
