    • 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.
    • 本发明的橡胶组合物通过将10〜200质量份的二氧化硅和1〜30质量份的具有硫原子的硅烷化合物混合而制备,所述硅烷化合物具有特定结构,使得有机氧基甲硅烷基在两端存在 分子和硫化物或多硫化物存在于分子的中心部分,聚合物为100质量份。 本发明的橡胶组合物在未硫化状态下具有较小的粘度,并提供优异的二氧化硅分散性。 当将该组合物用作轮胎胎面的材料时,可以获得在湿路面上显示出优异的耐磨性,小滚动阻力和优异的制动性能和操纵稳定性的轮胎。
