    Abstract: The invention is a high molecular weight polyether polyol prepared by the reaction of one or more compounds having one or more active hydrogen compounds with one or more alkylene oxides in the presence of a catalyst comprising calcium having counterions of carbonate and a C6-10 alkanoate in a solvent or dispersant which does not contain active hydrogen atoms. The polyether polyol prepared preferably has an equivalent weight of from about 10,000 to about 30,000, a polydispersity of 1.3 or less and a residual catalyst level of from more than 0 to about 2000 parts per million (ppm). In another embodiment the invention is a process for preparing such high molecular weight polyether polyols. The process comprises first, contacting one or more compounds having one or more active hydrogen atoms with one or more alkylene oxides in the presence of a catalyst. The catalyst comprises calcium having counterions of carbonate and a C6-10 alkanoate in a solvent, wherein the solvent does not contain active hydrogen atoms. The mixture is exposed to conditions at which the alkylene oxides react with the compound containing more than one active hydrogen atoms such that a polyether polyol is prepared which has an equivalent weight of from about 10,000 to about 30,000, a polydispersity of about 1.3 or less and a residual catalyst level of from more than 0 to about 2,000 (ppm).
