Rubber composition, which can be used for the manufacture of tires, based on at least one diene elastomer, one reinforcing filler, one vulcanization system and one maleimide compound, characterized in that the said maleimide compound is a polymaleimide of formula: in which: Use of such a composition for the manufacture of a finished article or of a semi-finished product made of rubber intended for a motor vehicle ground-contact system, in particular of a tire.

Rubber composition containing a polymaleimide compound

A rubber composition based on at least a diene elastomer, a reinforcing filler and a siloxane polysulfide of the general formula (I) below: in which: The invention also concerns a process for preparing a rubber composition having an improved reversion resistance, a finished article intended for a suspension system of an automotive vehicle, in particular a tire.

Rubber composition comprising a siloxane polysulfide

The present invention is directed to a rubber composition that is useful for the manufacture of tires, where the composition is based on a diene elastomer, a reinforcing inorganic filler, and a coupling system. The coupling system comprises a polysulfurized alkoxysilane ('PSAS') coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine and a guanidine derivative. The present invention is further directed to tires and semi-finished products for tires comprising a rubber composition according to the invention. The invention is also directed to a coupling system (inorganic filler/diene elastomer) for a rubber composition based on a diene elastomer reinforced by an inorganic filler, where the coupling system comprises a polysulfurized alkoxysilane (PSAS) coupling agent in association with a 1,2-dihydropyridine and a guanidine derivative.
