Abstract
The present invention relates to a rubber composition including (A) at least one rubber component selected from the group consisting of a synthetic rubber and a natural rubber; (B) a polymer of farnesene; and (C) carbon black having an average particle size of from 5 to 100 nm, a content of the carbon black (C) in the rubber composition being from 20 to 100 parts by mass on the basis of 100 parts by mass of the rubber component (A).
Claims9
A rubber composition comprising:
- (A) at least one rubber component selected from the group consisting of a synthetic rubber and a natural rubber;
- (B) a polymer of farnesene having a weight-average molecular weight of from 25,000 to 500,000 and a melt viscosity of from 0.1 to 3,000 Pa·s as measured at 38° C.;
- and
- (C) carbon black having an average particle size of from 5 to 100 nm,
- wherein a content of the polymer (B) in the rubber composition is from 0.1 to 100 parts by mass on the basis of 100 parts by mass of the rubber component (A), and
- wherein a content of the carbon black (C) in the rubber composition is from 20 to 100 parts by mass on the basis of 100 parts by mass of the rubber component (A).
