| titleOfInvention | Method for preparing polyetherester carbonate polyol |
| abstract | The subject of the present invention is a process for the preparation of polyetherester carbonate polyols by catalytic addition of alkylene oxide and carbon dioxide to H-functional starter substances in the presence of a double metal cyanide catalyst, comprising the following steps: (α) A partial amount of H-functional starter material and/or H-functional-free suspension medium is first loaded into the reactor, optionally together with a DMC catalyst, (γ) during the reaction process the alkylene oxide and optionally carbon dioxide The metering into the reactor is characterized in that the lactide is metered into the reactor in step (γ). |
