摘要
本文以聚乙二醇和环氧丙烷为原料，用常压法合成了一系列“氧化丙烯－氧化乙烯－氧化丙烯”嵌段共聚醚（PEP）；对合成产物进行了结构表征，对反应影响因素进行了探讨，并对产物的表面活性性能进行了测定研究。
A selies of block copoly(PEP)s were prepared from polyethylene glycol and propylene oxide at atmospheric pressure,the products were characterised,the factor of influence feaction were researched,and the surface properties of products have been measured too.
