METHOD FOR PREPARING POLYETHER CARBONATE ALCOHOLS

A method for preparing polyether carbonate alcohols by attaching cyclic carbonate to an H-functional starter substance in the presence of a catalyst, characterized in that a tribasic alkali- or alkaline earth metal phosphate is used as the catalyst, the alkali metal being selected from potassium or...
