摘要： The invention is a process for preparing polyether carbonate polyols byaddition of alkylene oxides and carbon dioxide onto one or more H-functional startersubstance (s) in the presence of a double metal cyanide catalyst or in the presence of ametal complex catalyst based on the metals zinc and / or cobalt, characterized in thatthat one or more H-functional starter substance (s) containing at least 1000 ppm ofcomponent K are continuously metered into the reactor during the reaction, componentC is selected from at least one compound containing a phosphorus-oxygen bond, or acompound of phosphorus, which can form by reaction with OH-functional compounds,one or more P-O bond (s).
