摘要:
The present invention relates to a process for the preparation of polyether carbonate polyols by catalytic copolymerization of carbon dioxide (CO2) with alkylene oxides in the presence of one or more H-functional starter substances with the aid of double metal cyanide (DMC) catalysts and in the presence of metal salts.
