Abstract: Disclosed herein are processes for producing polyurethanes including mixing (a) polyisocyanate, (b) polymeric compounds having isocyanate-reactive groups, (c) optionally catalysts, (d) polymeric amines of general formula H2N—W-NR-[W-NR]l-[Q-NR]m-[S—NR]n-W-NH2 and optionally (e) blowing agents, (f) chain extenders and/or crosslinking agents and (g) auxiliaries and/or additives to form a reaction mixture and reacting the reaction mixture to afford the polyurethane where the polydispersity of the polymeric amines (d) is at least 1.2. Further disclosed herein are a polyurethane produced by the process, a method of using such a polyurethane in enclosed spaces and a composition including (b) polymeric compounds having isocyanate-reactive groups, (c) catalysts and (d) polymeric amines of general formula H2N—W-NR-[W-NR]l-[Q-NR]m-[S—NR]n-W-NH2 and blowing agents including water, where the polydispersity of the polymeric amines (d) is at least 1.2.
