METHOD FOR PRODUCING POLYOXYALKYLENE POLYOL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polyoxyalkylene polyol in high productivity. SOLUTION: A polyoxyalkylene polyol is produced by the addition polymerization of an epoxide compound to an active hydrogen compound in the presence of a compound catalyst having P=N bond. A mixed active hydrogen compound composed of a non-oxyalkylenated active hydrogen compound and an oxyalkylenated active hydrogen compound is used as the active hydrogen compound and the concentration of the active hydrogen group of the oxyalkylenated active hydrogen compound is 0.01-20 mol% based on the active hydrogen group of the mixed active hydrogen compound.
