"RUBBER COMPOSITION, PROCESSES FOR THE PREPARATION OF A RUBBER COMPOSITION AND FOR THE COUPLING OF A WHITE LOAD AND A DIETIC ELASTOMER IN A RUBBER COMPOSITION, USING A COMPOSITION OF RUBBER, NUTRITION, PUMPKIN, PUMPKIN, PUNCH PNEUMATIC WHEELS AND USE OF A COMPOUND ". Rubber composition based on at least one dienic elastomer, a white filler as a reinforcement filler, a coupling agent (white filler / elastomer) at least bifunctional that can be grafted onto the elastomer using an X function, a said function X consisting of an ester function of an unsaturated 244 - 225 acid carrier in the sym position of a carbonyl group and which has the general formula (X) in which R, R ^ 1 ^ and R ^ 2 ^ identical or different, each represents a monovalent hydrocarbon radical or, in the case of R ^ 1 ^ and R ^ 2 ^, a hydrogen atom equally. Tire or semi-finished product, especially tread, for tires involving a rubber composition according to the invention.
