  The present invention relates to a process for the production of polyurethanes where (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts, (d) sulfur-carbon compounds selected from the group consisting of sulfinic acid derivatives of the general formula (I) and/or sulfonic acid derivatives according to the general formula (II) where R1 and R2 can be identical or different and are respectively any desired substituted or unsubstituted hydrocarbon moiety, with the proviso that the carbon atom bonded to the sulfur atom is an aliphatic carbon atom, and optionally (e) blowing agent, (f) chain extender and/or crosslinking agent, and (g) auxiliaries and/or additives are mixed to give a reaction mixture, and the reaction mixture is allowed to complete a reaction to give the polyurethane. The present invention further relates to polyurethanes produced by this process and to the use of these polyurethanes in the interior of means of transport.

  本发明涉及一种生产聚氨酯的工艺，在该工艺中，(a) 多异氰酸酯，(b) 具有对异氰酸酯有反应性基团的高分子化合物，(c) 催化剂，(d) 硫碳化合物，这些化合物选自由通式(I)的亚硫酸衍生物组成的组 和/或磺酸衍生物组成的组 其中 R1 和 R2 可以相同或不同，并分别是任何所需的取代或未取代的烃基，但与硫原子结合的碳原子必须是脂族碳原子，可选 (e) 发泡剂，(f) 扩链剂和/或交联剂，以及 (g) 助剂和/或添加剂混合得到反应混合物，让反应混合物完成反应得到聚氨酯。本发明还涉及通过该工艺生产的聚氨酯以及这些聚氨酯在运输工具内部的用途。
