  • Publication number: 20200317860
    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.

  • Publication number: 20200277435
    Abstract: The present invention relates to the use of diblock copolymers as surfactants, and to a method for producing diblock copolymers, containing a hydrocarbon-containing block A and a polyether carbonate-containing block B, by attaching alkylene oxide and carbon dioxide to H-functional starters in the presence of a double metal cyanide catalyst, characterized in that the H-functional starter has an OH functionality of 1, and the H-functional starter is selected from one or more compounds of the group of monofunctional alcohols having 10 to 20 carbon atoms, and no further catalyst is used in addition to the DMC catalyst.
