摘要： Disclosed herein is a process for producing polyurethanes including mixing (a) aromatic polyisocyanate with (b) polymeric compounds having isocyanate-reactive groups, (c) optionally chain extender and/or crosslinking agent, (d) catalyst, (e) 0.1% to 5% by weight, based on the total weight of the components (a) to (f), of at least one cyclic urea structure of general formula 1




where —X— represents a substituted or unsubstituted, 3-membered radical and R represents a radical (f) optionally blowing agent and (g) optionally additives to afford a reaction mixture and reacting the reaction mixture to afford the polyurethane. Further disclosed herein are a polyurethane obtainable by such a process and a method of using such a polyurethane foam for producing cushions, seat pads and mattresses.
