前言本文所讨论的高活性聚醚,是在高分子量三羟基环氧丙烷聚醚(PPO)的分子链末端,再连接环氧乙烷单元,而制成的一种伯羟基含量较高的改性聚醚(记作PPO-E),仍属于环氧化物聚醚类。鉴于环氧化物聚醚用途广泛,又是聚氨酯工业中的重要原料。近年来,在凝胶渗透色谱(GPC)领域内,也开始对环氧化物聚醚的分子量分布和齐聚物含量进行研究。 Preface This article discusses the high activity of polyether, is the molecular chain of high molecular weight trihydroxypolyoxypropylene polyether (PPO) and then connected to ethylene oxide units, and made a higher content of primary hydroxyl modified Polyethers (referred to as PPO-E), still belong to epoxide polyethers. Given the wide range of uses of epoxides, polyurethanes are also an important raw material in the polyurethane industry. In recent years, molecular weight distribution and oligomer content of epoxide polyethers have also been studied in the field of gel permeation chromatography (GPC).
