| 发明名称 | Rubber composition, production method therefor and tire | ||
| 摘要 | Objects of the present invention are to provide a rubber composition that can obtain a rubber elastic body having small rolling resistance and excellent impact resilience and a method for producing the same, and to provide a tire having small rolling resistance and excellent impact resilience. The rubber composition of the present invention is obtained by kneading a conjugated diene polymer (A) having a group with bonding reactivity to silica only at one site of one molecule of the polymer, a polymer (B) having groups with bonding reactivity to silica at a plurality of sites of one molecule of the polymer, and a filler (C) containing silica. | ||
