DOUBLE METAL CYANIDE CATALYSTS FOR THE PREPARATION OF POLYETHER POLYOLS

摘要

The present invention relates to novel double metal cyanide (DMC) catalysts for the preparation of polyether polyols by a polyaddition reaction between alkylene oxides and starter compounds having active hydrogen atoms, wherein the catalyst contains a) at least one double metal cyanide compound, b) at least one organic complexing ligand and c) at least one fluorine-containing complexing ligand.
