Clear, amine-initiated polyether polyols are made by epoxidizing an amine in the presence of an alkali metal hydroxide catalyst. After the desired degree of epoxidation has been achieved, a hydroxy-carboxylic acid is added to the epoxidized mixture in an amount sufficient to neutralize any remaining alkali metal hydroxide. The polyols produced in this manner are particularly useful for the production of polyurethane and polyisocyanurate foams.
