Abstract

The invention relates to a method for producing polyether polyols with dense molar mass distribution and low viscosity by polyaddition of alkylene oxides to starter compounds having active hydrogen atoms by means of DMC catalysis. The inventive method is further characterized by a substantially reduced induction period.
