    摘要： The invention relates to a method for producing polyether carbonate polyols, comprising the step of reacting alkylene oxide with carbon dioxide in the presence of an h-functional starter compound and double metal cyanide catalyst. The invention is characterized in that the method comprises the following steps: (α) optionally, pre-treating the double metal cyanide catalyst (DMC catalyst) at a temperature of 50 to 200° C. and/or reduced pressure (absolute) of 10 mbar to 800 mbar; (β) bringing the double metal cyanide catalyst in contact with suspension means, and furthermore, with alkylene oxide in the first reactor thus obtaining a first reaction mixture, and (γ) continuous added dosing of the first reaction mixture, alkaline oxide, and carbon oxide, and optionally, h-functional starter compound in a second reactor, wherein in at least one of the steps (β) or (γ), at least one h-functional starter compound is used, and wherein reaction products formed in step (γ) are continuously removed from the second reactor.

    摘要： The present invention relates to a method for preparing polyether carbonate polyols by the addition of alkylene oxides and carbon dioxide onto H-functional starter compounds. The method is characterized in that at least one urethane alcohol according to formula (II) is used as an H-functional starter compound, wherein R represents a linear or branched C2 to C24-alkylene which can be optionally interrupted by heteroatoms such as O, S or N and can be substituted; R2 represents a linear or branched C2 to C24-alkylene which can be optionally interrupted by heteroatoms such as O, S or N and can be substituted; R3 represents H, linear or branched C1 to C24-alkyl, C3 to C24-cycloalkyl, C4 to C24-aryl, C5 to C24-arylalkyl, C2 to C24-alkenyl, C2 to 24-alkinyl, that can each be optionally interrupted by heteroatoms such as O, S, or N and/or may each he substituted with alkyl, aryl, and/or hydroxyl. The invention further relates to polyether carbonate polyols that contain one urethane group, said polyether carbonate polyols being obtainable by the method according to the invention; the use of the polyether carbonate polyols according to the invention for preparing a polyurethane polymer; and the resulting polyurethane polymers.
