Abstract
A rubber composition based on at least: from 50 to 100 phr of one or more diene elastomers, referred to as very low glass transition temperature (Tg) diene elastomers, having a Tg within a range of from −110° C. to −70° C., selected from butadiene homopolymers, copolymers of butadiene and of a vinylaromatic monomer, having a content of vinylaromatic units of between 0 and 5% by weight, and mixtures thereof a reinforcing filler a crosslinking system; and from 50 to 150 phr of at least one hydrocarbon resin predominantly composed of units derived from terpene and phenol monomers, the resin having a content of aromatic protons of greater than 15%.
