Abstract
A rubber composition comprising at least an elastomer matrix predominantly comprising a highly saturated diene elastomer, which functionalized highly saturated diene elastomer is a copolymer comprising ethylene units and units of a 1,3-diene in which the ethylene units represent at least 50 mol % of the monomer units of the copolymer, preferably at least 60 mol %, a reinforcing filler containing silica, a coupling agent, a crosslinking system, and a liquid butadiene polymer functionalized by at least one alkoxysilyl function, having a number-average molar mass (Mn) of greater than or equal to 1000 g/mol.

- a reinforcing filler containing silica;
- a coupling agent;
- a crosslinking system;
- and
- a liquid butadiene polymer functionalized by at least one alkoxysilyl function, having a number-average molar mass of greater than or equal to 1000 g/mol.
