Abstract

The present invention relates to polyurethanes obtained by mixing to give a reaction mixture of (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts comprising incorporable amine catalysts, (d) phosphoric esters, polyphosphates, phosphonic esters, and/or phosphorous esters, and optionally (e) blowing agents, (f) chain extenders and/or crosslinking agents, and (h) auxiliaries and/or additives, and completing the reaction of the reaction mixture to give the polyurethane. The invention further relates to a process for producing these polyurethanes and to their use in automobile interiors.
