METHOD FOR PRODUCING POLYOL MIXTURES

摘要

The invention relates to a method for producing polyol mixtures containing polyether carbonate polyol and urethane group-containing polyol, characterized in that: (i) in a first step, one or more alkylene oxides and carbon dioxide are added in the presence of at least one DMC catalyst to one or more H-functional starter substances ("copolymerization"); and (ii) in a second step, at least one amino-functional substance is added to the raw mixture obtained in step (i). The invention further relates to a method for producing polyurethane from these mixtures.
