A process is disclosed for preparing hydroxyethers of epoxidized polybutenes wherein the epoxide groups of said epoxidized polybutenes are about 70% trisubstituted and about 20% tetrasubstituted. Hydroxyl compounds are reacted with epoxidized polybutenes to obtain compounds of increased flexibility, water resistance, lubricity, and adhesion as compared with said hydroxyl compounds.
