| 摘要 |
The present invention relates to a process for preparing polyurethanes in which (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts, (d) sulfur-amine complexes, obtainable by reacting compounds which contain at least one amine group (d1) with sulfur dioxide (d2) and optionally (e) blowing agents, (f) chain extenders and/or crosslinking agents and (g) auxiliaries and/or additives are mixed to give a reaction mixture and the reaction mixture is allowed to react to give the polyurethane. The present invention further relates to polyurethanes which have been produced by such a process and to the use of such polyurethanes in the interior of means of transport. |
