A process for the production of polyurethanes is disclosed. In the process, (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts, and (d) sulphur-dioxide-amine complexes obtainable by reaction of compounds (d1) comprising at least one amino group with sulfur dioxide (d2), are mixed to give a reaction mixture, and the reaction mixture is allowed to complete a reaction to give a polyurethane. Compounds (d1) may optionally further comprise (e) blowing agent, (f) chain extender and/or crosslinking agent, and (g) auxiliaries and/or additives. Polyurethanes produced by this process and the use of these polyurethanes are also disclosed, including use of these polyurethanes in the interior of means of transport.
