| 摘要 |
The invention relates to a method for producing polyurethanes, wherein (a) polyisocyanate, (b) polymer compounds with groups which are reactive towards isocyanates, (c) catalysts, (d) sulfur-carbon compounds, selected from the group consisting of sulfinic acid derivatives according to the general formula (I) and/or sulfonic acid derivatives according to the general formula (II), in which R1 and R2 can be the same or different and each represents any substituted or unsubstituted hydrocarbon group with the proviso that the carbon atom which is bonded to the sulfur atom is an aliphatic carbon atom, and optionally (e) a propellant, (f) chain-extending and/or crosslinking agents, and (g) auxiliary agents and/or additives are mixed into a reaction mixture, and the reaction mixture is allowed to completely react into the polyurethane. The invention further relates to polyurethanes which have been produced according to such a method and to the use of such polyurethanes in the interior of transportation means. |
