    Abstract: Highly functional aromatic polyisocyanates are prepared by reacting aromatic polyisocyanates, if required as a mixture with further mono- and/or polyisocyanates, with addition of catalytic acidic substances and water, by a process wherein the aromatic polyisocyanates used comprise at least one tolylene diisocyanate and the catalytic acidic substance used is at least one alkyl and/or aralkyl phosphate, and the process is carried out in such a way that the water is added with a temperature/time gradient increase from 5 to 60°/hour and until an isocyanate modification of the starting NCO terminal groups from 1 to 80% is established. The highly functional aromatic polyisocyanates prepared by this process are used for the preparation of polyurethane foams, in particular flexible polyurethane foams.

    Abstract: Flameproofed flexible polyurethane foams are prepared by reacting organic and/or modified organic polyisocyanates (a) with a polyetherol mixture (b) and, if required, further compounds (c) having hydrogen atoms reactive toward isocyanates, in the presence of water and/or other blowing agents (d), catalysts (e) stabilizers (f), flameproofing agents (g) and, if required, further assistants and additives (h), by a process in which the polyetherol mixture (b) comprises b1) at least one polyetherol which is at least difunctional and based on propylene oxide and/or butylene oxide and ethylene oxide, the ethylene oxide content being less than 25% by weight, based on the total amount of alkylene oxide used, has an OH number of from 20 to 80 mg KOH/g and contains more than 70% of primary OH groups and b2) at least one polyetherol which is based on propylene oxide and/or butylene oxide and ethylene oxide, has an OH number of more than 30 mg KOH/g and contains less than 70% of primary OH groups, and melamine, if desired as a mixture with further flameproofing agents, is used as flameproofing agent (g). The flameproofed flexible polyurethane foams prepared by this process can be used as upholstery for furniture and vehicle seats.

    Abstract: A homogeneous, demixing-stable polyol component comprising at least two relatively high molecular weight compounds containing at least two reactive hydrogen atoms and, if desired, low molecular weight chain extenders and/or crosslinkers and also, if desired, blowing agents, catalysts and further auxiliaries and/or additives is prepared by adding at least one amine and at least one organic and/or modified organic isocyanate to this component. This polyol component is useful for producing polyurethanes, in particular compact and foamed polyurethanes.

    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.
