Abstract: The invention relates to graft polyols with a bimodal particle size distribution and a total solid content of between 5 and 65 wt. %. Said polyols contain small particles with a particle diameter of between 0.05 and 0.7 mu m and large particles with a particle diameter of between 0.4 and 5.0 mu m, whereby the peaks of the large and small particles measured during a representation according to the light-scattering analysis method do not overlap. The total solid content with the defined particle sizes consists of a volumetric fraction of between 5 and 45 % small particles and a volumetric fraction of between 95 and 55 % large particles, said volumetric fractions totalling 100 %. The invention also relates to a method for producing graft polyols of this type and to the use thereof for producing polyurethanes.
