Beschreibung
Zusammenfassung:	The invention relates to a mixture of nonylated diphenylamines, especially dinonylated diphenylamines, and to a technically advantageous methodological process for the preparation of that mixture by using acid catalysts in small quantities. The mixture is used as an additive for stabilizing organic products that are subjected to oxidative, thermal and/or light-induced degradation.
