This invention relates to modified Group IIIB metal-containing bimetallic or polymetallic catalysts and the use thereof in the preparation of alkoxylation products, i.e., condensation reaction products of alkylene oxides and organic compounds having at least one active hydrogen. In another aspect of this invention, processes are provided for preparing the modified Group IIIB metal-containing bimetallic or polymetallic catalysts for alkoxylation using a Group IIIB metal or a Group IIIB metal-containing compound as sources for the catalytically-active Group IIIB metal. In a further aspect of this invention, processes are provided for preparing alkoxylation products that have beneficial, narrow molecular weight ranges using the modified Group IIIB metal-containing bimetallic or polymetallic catalysts.
