| titleOfInvention | Method for producing polyetherester polyols |
| abstract | A subject of the invention is a method for producing a polyetherester polyol by addition of alkylene oxide and lactone to H-functional starter substance in the presence of a double metal cyanide catalyst, wherein a suspension medium containing no H-functional groups is first initially charged in a reactor, and an H-functional starter substance is subsequently continuously metered in to the reactor during the reaction, and wherein the lactone is a 4-membered cyclic lactone. A further subject is also the polyetherester polyol obtainable according to the method according to the invention, and also polyurethanes which can be produced therefrom. |
