Double-metal cyanide catalysts for preparing polyether polyols |
摘要 |
The invention relates to double-metal cyanide (DMC) catalysts for preparing polyether polyols by the polyaddition of alkylene oxides on to starter compounds containing active hydrogen atoms, wherein the DMC catalysts are composed of: a) at least one DMC compound; b) at least one organic complexing ligand which is not a coronand; and c) at least one coronand. The DMC catalysts of the present invention have increased activity compared to known catalysts.
