Abstract
This invention relates to modified Group IIA metal-containing (other than calcium-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 IIA metal-containing bimetallic or polymetallic catalysts for alkoxylation using a Group IIA metal or a Group IIA metal-containing compound as sources for the catalytically-active Group IIA 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 IIA metal-containing bimetallic or polymetallic catalysts.
