Rubber composition comprising specific hydrocarbon resin

摘要: The invention relates to a rubber composition based on at least one elastomer comprising from 50 100 phr of or more copolymers butadiene and vinylaromatic monomer, having content units between 0 5% by weight Tg within range extending -110 -70 degree centigrade, reinforcing filler, crosslinking system an optionally hydrogenated hydrocarbon-based resin, predominantly composed selected the group consisting cyclopentadiene, dicyclopentadiene, methylcyclopentadiene mixtures thereof, said resin average molecular Mz less than 2000 g/mol glass transition temperature expressed in centigrade such that >= 80-2*(%HA), where %HA represents aromaticprotons is 15 150 phr.
