METHOD FOR PRODUCING ALKOXYLATED POLYETHER POLYOLS

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing alkoxylated polyether polyols. SOLUTION: In a method for producing polyether polyols having its terminal hydroxy groups alkoxylated by reacting polyether polyols with an alkali metal alkoxide, the polyether polyols and the alkali metal alkoxide are mixed in advance and then fed to a reactor with simultaneous dealcoholation.
