The effectiveness of aromatic amines as antioxidants for SKS 30ARK (SBR) increased with increasing electron donor properties of para substituents (Br, Me, OMe, NMe2) on the Ph rings, with increasing ¦Ð electron d. of the aromatic rings, and on introducing ortho or para NO2 groups in Ph2NH. The antioxidative action of the nitro derivatives was attributed to interaction of the NO2 groups with C radicals of the oxidizing polymer. Other amines interacted with O radicals. A synergistic antioxidative effect was observed for mixts of p-O2NC6H4NHPh [836-30-6] and N-¦Â-naphthyl-N-phenylamine??[135-88-6].
