Polyurethane mit reduzierter Aldehydemission

Abstract: The present invention relates to a method for preparing polyurethanes, in which method (a) polyisocyanate, (b) polymeric compounds comprising groups that are reactive to iso- <1l cyanates, (c) catalysts, (d) compounds of general formula R(-S)n, where R represents any group, n represents any number between I and 8, and S represents a group according to formula I: and optionally (e) blowing agents, (f) chain lengthening- and/or crosslinking agents and (g) auxiliaries and/or additives are mixed to form a reaction mixture, and the reaction mixture is allowed to fully react to form the polyurethane
