    摘要： Flexible foams based on polyisocyanate polyaddition products are produced by reacting polyisocyanates with compounds which are reactive toward isocyanates in the presence of catalysts, blowing agents and, if desired, flame retardants, auxiliaries and/or additives, wherein polyether polyalcohols (c) which are obtainable by addition of alkylene oxides onto substances containing active hydrogens are used as substances which are reactive toward isocyanates, where, in a first stage, at least one substance (a) containing 2 or 3 active hydrogens is reacted with at least one alkylene oxide in the presence or absence of catalysts, subsequently at least one substance (b) which contains at least four active hydrogens and, if desired, further catalyst is added to the reaction mixture from the first stage and this mixture is then reacted in a second stage with at least one alkylene oxide.

    摘要： 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 μm and large particles with a particle diameter of between 0.4 and 5.0 μm, 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.
