Abstract

The invention relates to new improved double-metal cyanide (DMC) catalysts for the preparation of polyether-polyols by polyaddition of alkylene oxides on to starter compounds containing active hydrogen atoms, the catalyst comprising a double-metal cyanide compound, an organic complexing ligand and 5 - 80 wt.%, based on the amount of catalyst, of a polyester.
For the preparation of polyether-polyols, the new improved catalysts have significantly shortened induction times and at the same time a greatly increased activity.
