<p>Rubber composition, especially for a tyre, based on at least one diene elastomer, a reinforcing filler, a crosslinking system and an antioxidant system, wherein said antioxidant system comprises at least two antioxidants“A”and“B”: A. an N-alkyl-N′-phenyl-para-phenylenediamine corresponding to the formula (I): B. a 4,4′-bis(alkylamino)triphenylamine corresponding to the formula (II): in which formulae, R1, R2 and R3, which are identical or different, each represent a linear or branched alkyl group having from 1 to 12 carbon atoms or a cycloalkyl group having from 5 to 8 carbon atoms, the A/B weight ratio being between 0.2 and 5.0. Such an antioxidant system gives the composition of the invention a better long-term resistance to fatigue and to crack propagation.</p> |
