Abstract: Polyurethane-polyisocyanurate compounds and processes for preparing polyurethane-polyisocyanurate compounds are disclosed herein. A process includes mixing component (a) polyisocyanate with component (b) a mixture obtainable by introducing an alkali metal or alkaline earth metal salt into a compound R—NH—CO—R′ containing urethane groups, where R is not hydrogen and is not COR″, component (c) compounds containing one or more epoxide groups, component (d) one or more compounds having at least two isocyanate-reactive groups, comprising compounds having NH2 and/or primary OH groups, and component (e) optionally fillers and other additives, to form a reaction mixture, and reacting said reaction mixture to form the polyurethane-polyisocyanurate compound, wherein the molar amount of alkali metal and/or alkaline earth metal ions in the reaction mixture per mole of urethane group in component (b) is 0.0001 to 3.5 and the isocyanate index is greater than 150. Use of polyurethane-polyisocyanate compounds for producing vehicle parts is also disclosed.

Abstract: The present invention relates to a process for preparing polyurethanes, in which (a) polyisocyanate, (b) polymeric compounds with groups that are reactive towards isocyanates, (c) catalysts, (d) 0.01 to 1% by weight of an aliphatic hydrocarbon (d1) having 2 to 15 carbon atoms which comprise at least one heteroatom selected from the group consisting of oxygen, nitrogen and sulfur, and at least one chlorine or bromine atom, and/or phosphoric acid ester (d2), (e) antioxidants and/or light stabilizers and optionally (f) blowing agents, (g) chain extenders and/or crosslinking agents and (h) auxiliaries and/or additives are mixed to give a reaction mixture and the reaction mixture is allowed to fully react to give the polyurethane, where the phosphoric acid ester corresponds to the general formula (R1—O)3—P═O, where the three radicals R1, independently of one another, are organic radicals which comprise one or more phenyl groups, one or more phosphoric acid groups (polyalkyl phosphate with ethylene oxide) or esters thereof and/or one or more atoms selected from the group consisting of nitrogen, oxygen, fluorine, chlorine and bromine. Furthermore, the present invention relates to polyurethanes obtainable by a process according to the invention and to the use of these polyurethanes in the interior of means of transport.
