Abstract
The present invention relates to a rubber composition based on at least an elastomer matrix predominantly comprising a highly saturated diene elastomer, a reinforcing filler, a vulcanization system, and a liquid butadiene polymer functionalized along the chain by pendent alkoxysilyl functions, having a number-average molar mass (Mn) greater than or equal to 1000 g/mol. The highly saturated diene elastomer is a copolymer of ethylene and of a 1,3-diene in which the ethylene units represent at least 50 mol % of the monomer units of the copolymer.

A rubber composition based on at least:
- an elastomer matrix predominantly comprising a highly saturated diene elastomer, which highly saturated diene elastomer is a copolymer of ethylene and a 1,3-diene in which ethylene units represent at least 50 mol % of monomer units of the copolymer;
- a reinforcing filler;
- a vulcanization system;
- and
- a liquid butadiene polymer functionalized along a chain by pendent alkoxysilyl functions, which are optionally completely or partially hydrolyzed, having a number-average molar mass Mn greater than or equal to 1000 g/mol.
