Abstract:
The present invention relates to a process for the preparation of polyether carbonate polyols from one or more alkylene oxides, carbon dioxide and optionally from one or more H-functional starter substances in the presence of at least one double metal cyanide catalyst, wherein the double metal cyanide catalyst comprises an unsaturated alcohol as a complexing ligand.
