Provided is a rubber composition comprising an inorganicnfiller, a compound having at least one group A reacting with anrubber and two or more groups B adsorbing on the inorganicnfiller described above in the same molecule, a compound havingnthe group A reacting with a rubber and an amino group in thensame molecule or acrylate or methacrylate having a specificnstructure and further comprising, if necessary, a silanencoupling agent. This makes it possible to provide a rubberncomposition which is excellent in the dispersibility of anninorganic filler, so that it does not elevate a viscosity of annon-vulcanized rubber and does not damage the processabilitynand which does not bring about roughening on the surface of anrubber and is improved in a storage modulus. |
