Rubber compositions comprising a specific combination of a coupling agent and a hydrocarbon-based resin

A rubber composition is based on at least: a diene elastomer; a reinforcing inorganic filler; an agent for coupling the reinforcing inorganic filler with the diene elastomer, said coupling agent being a blocked mercaptosilane of formula (I), as described in the claims; a hydrocarbon-based resin pred...

More Information
Summary:A rubber composition is based on at least: a diene elastomer; a reinforcing inorganic filler; an agent for coupling the reinforcing inorganic filler with the diene elastomer, said coupling agent being a blocked mercaptosilane of formula (I), as described in the claims; a hydrocarbon-based resin predominantly composed of monomers chosen from the group consisting of cyclopentadiene, dicyclopentadiene, methylcyclopentadiene and mixtures thereof, and a crosslinking system. A semi-finished article and a tire may comprise at least one such rubber composition.
