Abstract
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 rubber component containing 30 to 95% by mass of a conjugated diene polymer (A) and 5 to 70% by mass of cross-linked rubber particles (B) with 20 to 100 parts by mass of silica (C) based on 100 parts by mass of the rubber component.
Claims7
A rubber composition, comprising:
- a rubber component;
- and
- silica,
- wherein the silica is included in an amount of from 20 to 100 parts by mass based on 100 parts by mass of the rubber component, and
- the rubber component comprises from 30 to 95% by mass of a conjugated diene polymer comprising a hydrocarbyloxysilyl group, and from 5 to 70% by mass of cross-linked rubber particles based on the total mass of rubber component.
