Abstract: A process for obtaining a grafted diene elastomer having functional groups along the chain, a rubber composition containing this grafted elastomer and having in particular improved hysteresis properties in the cross-linked state, a preparation process for this composition, a tire tread made from this composition and a tire of reduced rolling resistance which incorporates this tread. A process for obtaining this grafted elastomer includes a radical grafting reaction carried out in solution or without a solvent by means of a reagent of the mercaptan type to graft functional groups on to the chain of a starting elastomer. The starting elastomer is treated with an antioxidant having at least one aromatic amine function before the grafting reaction, so that the grafted elastomer has a macrostructure which is practically identical to that of the starting elastomer. A rubber composition containing the grafted diene elastomer includes a reinforcing inorganic filler, and the grafted elastomer preferably has a molar ratio of units originating from conjugated dienes greater than 30%.
