Method for preparing polyether carbonate polyol |
| abstract |
The present invention relates to a process for the preparation of polyether carbonate polyols, (i) wherein one or more alkylene oxides are combined in the presence of a double metal cyanide catalyst or in the presence of a metal complex catalyst based on metallic zinc and/or cobalt and carbon dioxide to one or more H-functional starter substances to obtain a reaction mixture containing said polyether carbonate polyol, characterized in that (ii) at least one component K is added to a In the resulting reaction mixture of the polyether carbonate polyol, wherein component K is selected from at least one phosphorus-oxygen bond-containing compound or a phosphorus compound that can form one or more P-O bonds by reacting with an OH functional compound . |
