    摘要: Process for preparing polyether alcohols by polymerization by means of double metal cyanide catalysts (DMC catalysts), characterized in that, before or during the polymerization, one or more, optionally mixed additives consisting of compounds having one or more aromatic structures which may be monosubstituted or else polysubstituted and which have at least one hydroxyl group on the aromatic system are added to the reaction mixture.
