RUBBER COMPOSITION

摘要

A rubber composition comprising a diene rubber and silica and being excellent in impact resilience, tensile characteristics, wear characteristics and processing characteristics, characterized in that (i) the silica is contained in an amount of 10 to 150 pts. by wt. per 100 pts. by wt. of the diene rubber and (ii) a silicone oil having a polar group in the side chain or at the end is further contained in an amount of 0.1 to 50 pts. by wt. per 100 pts. by wt. of the silica; and a process for producing the composition.
