Abstract: Deactivation of amine catalysts in polyisocyanate polyaddition products (PIPAP) after their preparation in order to avoid the formation of primary amines, especially primary aromatic amines, by means of additives which decrease the content of these amines, especially in soft polyurethane foams, i.e. by addition of groups I, II, and or VIII subgroups, is new.

Abstract: According to the inventive method, the polyurethane foams are produced by reacting isocyanates with compounds that react with isocyanates in the presence of foaming agents and optionally, catalysts, additives and/or auxiliary agents. The method is characterised in that the reaction is carried out in the presence of at least one of the following compounds (i): alpha , beta -unsaturated carboxylic acid, alpha , beta -unsaturated carboxylic acid derivative, alpha , beta -unsaturated ketone and or alpha , beta -unsaturated aldehyde.
