四氢呋哺和环氧丙烷在五氯化锑存在下,开环聚合成的共聚醚二醇,是制备聚氨酯橡胶、泡沫、粘合剂、涂料等的重要原料。本文考查了聚合温度和时间、原料配比、催化剂和分子量调节剂用量的影响。从而得出不同分子量和质量稳定的四氢呋喃—环氧丙 Tetrahydrofuran and propylene oxide in the presence of antimony pentachloride, the ring-opening polymerization of copolyether glycol, is the preparation of polyurethane rubber, foam, adhesives, coatings and other important raw materials. This article examines the polymerization temperature and time, the ratio of raw materials, catalysts and molecular weight regulator dosage. Thus come to different molecular weight and quality of tetrahydrofuran - glycidoxypropane
