摘要：The invention relates to a method for producing polyether carbonate polyols,(i) one or more alkylene oxide(s) and carbon dioxide being added to one or more H-functional starter substance(s) in the presence of a double metal cyanide catalyst or inthe presence of a metal complex catalyst based on the metals zinc and/or cobalt, areaction mixture containing the polyether carbonate polyol being obtained,characterized in that (ii) at least one component K is added to the obtained reactionmixture containing the polyether carbonate polyol, wherein component K is selectedfrom at least one compound that contains a phosphorus-oxygen bond or a compound ofphosphorus that can form one or more P—O bonds by reaction with OH-functionalcompounds.
