Rubber composition comprising hybrid particles
Résumé
The invention concerns a rubber composition comprising at least a diene elastomer, a reinforcing filler and a cross-linking system characterised in that the reinforcing filler comprises hybrid particles, each particle comprising at least an organic portion and an inorganic portion: - the organic portion consisting of a polymer comprising recurring units derived from a vinyl compound, - the inorganic portion consisting of silica, - the two portions being bonded by a coupling agent likely to form the bond between the surface of the silica and said polymer, - the average size of each of the portions being between 5nm and 1 μm.
