    摘要： Provided is a rubber composition comprising an inorganic filler, a compound having at least one group A reacting with a rubber and two or more groups B adsorbing on the inorganic filler described above in the same molecule, a compound having the group A reacting with a rubber and an amino group in the same molecule or acrylate or methacrylate having a specific structure and further comprising, if necessary, a silane coupling agent. This makes it possible to provide a rubber composition which is excellent in the dispersibility of an inorganic filler, so that it does not elevate a viscosity of a non-vulcanized rubber and does not damage the processability and which does not bring about roughening on the surface of a rubber and is improved in a storage modulus.

    摘要： The rubber composition of the present invention is prepared by mixing 10 to 200 parts by mass of silica and 1 to 30 parts by mass of a silane compound having sulfur atom, which has a specific structure such that an organooxysilyl group is present at both ends of the molecule and sulfide or a polysulfide is present at the central portion of the molecule, with 100 parts by mass of a polymer. The rubber composition of the present invention has a small viscosity in the unvulcanized condition and provides excellent dispersion of silica. When this composition is used as a material for a tire tread, a tire exhibiting excellent abrasion resistance, a small rolling resistance and excellent braking property and steering stability on wet roads, can be obtained.
