    Abstract: PROBLEM TO BE SOLVED: To produce a foamed plastic material based on a polyisocyanate polyaddition product by reacting an isocyanate compound with an isocyanate- reacting compound in the presence of a catalyst and optionally an auxiliary and/or an additive. SOLUTION: This method for producing a polyurethane foam comprises reacting an isocyanate compound with an isocyanate-reacting compound in the presence of a catalyst, etc. Therein, (i) an isocyanate having an isocyanurate structure and/or a biuret structure is used as the isocyanate compound. (ii) The isocyanate-reacting compound herein used is at least one kind of diol and/or polyol, having a mol.wt. of 400-8,000 and containing primary hydroxyl groups in an amount of at least 50% based on all hydroxyl groups contained in the compound. (iii) At least one kind of compound having at least one primary amino group, and a diol and/or a triol having a mol.wt. of

    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 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.
