Abstract: 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.

The coupling system comprises a polysulfurized alkoxysilane (“PSAS”) coupling agent (inorganic filler/diene elastomer) associated with an aldimine having the general formula R—CH═N—R 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 an aldimine having the general formula R—CH═N—R and a guanidine derivative.

Abstract: The present invention provides for a coupling system (white filler/diene elastomer) for a rubber composition based on diene elastomer reinforced with a white filler, formed by the association of a polysulphurized alkoxysilane, an enamine and a guanidine derivative. The invention also provides a rubber composition usable for the manufacture of tires, comprising, as base constituents, one or more diene elastomer(s), a reinforcing white filler, a polysulphurized alkoxysilane coupling agent (white filler/diene elastomer), with which are associated an enamine and a guanidine derivative. Also provided is a process for preparing such a rubber composition, and a tire or semi-finished product, in particular a tread for a tire, comprising a rubber composition according to the invention.
