PROCESS FOR PREPARING POLYETHER CARBONATE ALCOHOLS

A process for preparing polyether carbonate alcohols by attaching cyclic ethylene carbonate to an H-functional starter substance in the presence of a catalyst, characterized in that at least one compound according to formulae X[VO3] (1), Y2[WO4] (2), or Y3[VO4] (3), wherein X=alkali metal, preferabl...

Zusammenfassung:	A process for preparing polyether carbonate alcohols by attaching cyclic ethylene carbonate to an H-functional starter substance in the presence of a catalyst, characterized in that at least one compound according to formulae X[VO3] (1), Y2[WO4] (2), or Y3[VO4] (3), wherein X=alkali metal, preferably potassium or cesium, and Y=potassium or cesium, is used.
