DOUBLE METAL CYANIDE CATALYSTS FOR PRODUCING POLYETHER POLYOLS

摘要

The invention relates to novel double metal cyanide (DMC) catalysts for producing polyether polyols by the polyaddition of alkylene oxides to active starter compounds that have active hydrogen atoms, whereby the catalyst contains a) double metal cyanide compounds, b) organic complex ligands and c) coronands. The inventive catalysts exhibit significantly increased activity during polyether polyol production.
