Abstract

PURPOSE: In the purification of crude high-molecular-weight polyalkylene oxide by removing an alkali metal compound, a solvent is added to reduce the viscosity of the reaction mixture and make the solution different in specific gravity from water and the aqueous layer is made acidic to facilitate the layer separation.
