Method for producing polyether carbonate polyols |
abstract |
The invention relates to a method for producing polyether carbonate polyols from one or more H-functional starting substances, from one or more alkylene oxides and carbon dioxide in the presence of at least one double metal cyanide catalyst, the cyanide-free metal salt, metal cyanide salt or both salts containing 0.3 to 1.8 mole base equivalents (based on 1 mole of the metal cyanide salt used for the catalytic synthesis) of alkaline metal hydroxide, metal carbonate and/or metal oxide. |
