Abstract:
This invention relates to modified bimetallic or polymetallic (other than Groups IA, IIA and IIB metals) 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 bimetallic or polymetallic catalysts for alkoxylation using a divalent or polyvalent metal or a divalent or polyvalent metal-containing compound as sources for the catalytically-active 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 bimetallic or polymetallic catalysts.
