Abstract (en)
[origin: WO2007121936A1] Tyre belt comprising a rubber composition based on at least one isoprenic elastomer, a reinforcing filler, a cross-linkage system and an anti-oxidant agent, characterised in that said anti-oxidant agent comprises a 4,4'- bis(alkylamino)-triphenylamine that fits the formula (I) in which R<SUP>1 </SUP>and R<SUP>2</SUP>, identical or different, each represent a linear or branched alkyl group, that has between 1 and 12 atoms of carbon or a cycloalkyl group that has between 5 and 8 atoms of carbon. Said anti-oxidant gives the inventive belt better long-term resistance to fatigue and to crack propagation.
