Method for producing polyether carbonate polyols |
abstract |
The invention relates to a method for producing polyether carbonate polyols from H-functional starter substances, alkylene oxides and carbon dioxide in the presence of DMC catalysts or metal complex catalysts based on metallic zinc and/or cobalt, wherein the purity of the carbon dioxide used is between 99.5000% by volume and 99.9449% by volume. |
