摘　　要：以含氮化合物、蔗糖、环氧丙烷等为原料，合成了硬泡用高官能度、低粘度聚醚多元醇。该聚醚多元醇２５℃粘度为３５００～４４００ｍＰａ· ｓ，理论官能度为５．６～６．４，羟值约为５００ｍｇＫＯＨ／ｇ。以该聚醚为基的聚氨酯硬泡，其主要性能与以通用聚醚为基的硬泡相当。High functionality polyether polyol with low viscosity for rigid foams was prepared from the mixture of nitrogenous compound, sugar and propylene oxide. The viscosity of polyether polyol at 25℃ is 3500 － 4400 mPa's, theoretical functionality is 5. 6 - 6. 4, hydroxyl value is 500 mgKOH/g approximately. The properties of PU rigid foam based on it are similar to the one based on commercial polyether polyol.
