Abstract: The invention relates to a method for producing polyether carbonate polyols by attaching alkylene oxides and carbon dioxide to one or more H-functional starters in the presence of a double-metal cyanide catalyst, characterized in that (alpha) a suspending agent which contains no H-functional groups is provided in a reactor, (ss) optionally, a moiety of alkylene oxide is added to the mixture from step (alpha) at temperatures of 90 to 150 DEG C., and the addition of the alkylene oxide compound is then interrupted; and (gamma) one or more H-functional starters are continuously metered into the reactor during the reaction.
