<p>The invention relates to novel bimetallic cyanide catalysts for producing polyether polyols by polyaddition of alkylene oxides to starter compounds with active hydrogen atoms. The catalyst contains a) bimetallic cyanide compounds, b) organic complex ligands which are different from c) and c) polyalkylene glycol sorbitan esters. The degree of activity of the inventive catalysts in the production of polyether polyols is increased considerably.</p> |
