摘要:
The invention relates to a process for the preparation of polyol mixtures comprising polyether carbonate polyol and polyol containing urethane groups, characterized in that (i) in a first step one or more alkylene oxides and carbon dioxide are added on to one or more H-functional starter substances in the presence of at least one DMC catalyst (“copolymerization”), and (ii) in a second step at least one amino-functional substance is added to the crude mixture formed in step (i), and a process for the preparation of polyurethane from these mixtures.
