Abstract
The invention relates to a rubber composition which comprises a highly saturated diene elastomer. The elastomer is a copolymer of ethylene and of a 1,3-diene comprising ethylene units which represent more than 50 mol % of the monomer units of the copolymer, a vulcanization system, a reinforcing filler containing a silica, and an azosilane coupling agent.
