Zusammenfassung:	The present invention concerns a method for producing polyurethane foams by reacting an isocyanate component with a component that is reactive to isocyanates and that comprises at least one polyether carbonate polyol, the reaction taking place in the presence of a non-amine antioxidant and an amine antioxidant. The invention also concerns polyurethane foams produced using the claimed method and the use of said foams. La présente invention concerne un procédé de production de mousses de polyuréthanne par réaction d'un composant isocyanate avec un composant réactif vis-à-vis des isocyanates qui comprend au moins un polyéther-carbonate-polyol, la réaction étant effectuée en présence d'un antioxydant non-amine et un antioxydant amine. L'invention concerne également des mousses de polyuréthanne produit selon le procédé de l'invention et leur utilisation.
