Alpha olefin oxide-capped polyether polyols are prepared by reacting a substantially anhydrous heteric or block copolymer of ethylene oxide and a lower alkylene oxide with an alpha olefin oxide in the presence of a catalyst. The capped polyether polyols are useful as thickeners for aqueous systems, such as water-based hydraulic fluids.
