본 발명은, 구름 저항이 작고, 우수한 반발 탄성을 갖는 고무 탄성체를 얻을 수 있는 고무 조성물 및 그의 제조 방법을 제공하는 것 및, 구름 저항이 작고, 우수한 반발 탄성을 갖는 타이어를 제공하는 것을 목적으로 하는 것이다. 본 발명의 고무 조성물은, 실리카에 대하여 결합 반응성을 갖는 기를 중합체 1분자의 1개소에만 갖는 공액 디엔계 중합체(A)와, 실리카에 대하여 결합 반응성을 갖는 기를 중합체 1분자의 복수 개소에 갖는 중합체(B)와, 실리카를 함유하는 필러(C)를 혼련함으로써 얻어진다.
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.
