| titleOfInvention | Method for preparing polyether carbonate polyols |
| abstract | The present invention relates to a process for preparing polyether carbonate polyols comprising the step of reacting an alkylene oxide with carbon dioxide in the presence of an H-functional starter compound and a double metal cyanide catalyst, comprising (α) H- A partial amount of functional starting material and/or a suspension medium free of H-functional groups is initially charged to the reactor in each case together with a DMC catalyst, (β) the mixture from step (α) is A partial amount of lene oxide is mixed at a temperature of 90° C. to 150° C., after which the addition of alkylene oxide is stopped, (γ) alkylene oxide, carbon dioxide, and a deactivated double metal cyanide catalyst and H a mixture resulting from (β) containing a functional starter compound, wherein the H-functional starter compound is a polyol having a number-average molar mass according to DIN 55672-1 of 550 to 2000 g/mol It relates to a method characterized in that continuously added to. |
