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.
