Abstract
This invention relates to modified 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 modified calcium-containing bimetallic or polymetallic catalysts for alkoxylation using calcium metal or a calcium-containing compound as sources for the catalytically-active calcium. In a further aspect of this invention, processes are provided for preparing alkoxylation products that have beneficial, narrow molecular weight ranges using the modified calcium-containing bimetallic or polymetallic catalysts.
