Abstract

Double metal cyanide (DMC) catalysts containing both (c) complex-forming polyether(s) and (d) complex-forming bile acid(s) or their salts, esters or amides in addition to (a) double metal cyanide(s) and (b) organic complex ligands other than (c) and (d). Independent claims are also included for: (i) a method for the production of DMC catalysts by reacting metal salts and metal cyanide salts with the other components listed above in aqueous solution and then isolating, washing and drying the catalyst; (ii) a method for the production of polyether-polyols by polyaddition of alkylene oxides with starter compounds containing reactive hydrogen atoms in presence of these catalysts; and (iii) polyether-polyols obtained by this method.
