Procedure for the preparation of polyethercarbonatopolols |
| abstract |
Process for the preparation of polyethercarbonate polyols by adding alkylene oxides and carbon dioxide to one or more H-functional starter substances in the presence of a double metal cyanide (DMC) catalyst, characterized in that (γ) during the addition are dosed from one or more H-functional starter substances as well as DMC catalyst continuously in the reactor, and the concentration of free alkylene oxide in the reaction mixture is 1.5% to 5.0% by weight, and the mixture The resulting reaction is continuously discharged from the reactor. |
