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 having a weight-average molecular weight of not less than 2,000 and less than 25,000; and (C) carbon black.
Claims10
A rubber composition, comprising:
- (A) at least one rubber component selected from the group consisting of a synthetic rubber and a natural rubber;
- (B) from 0.1 to 100 parts by mass of a polymer of farnesene having a weight-average molecular weight of not less than 2,000 and less than 25,000, based on 100 parts by mass of the rubber component (A);
- and
- (C) from 0.1 to 100 parts by mass of carbon black having an average particle size of from 5 to 100 nm, based on 100 parts by mass of the rubber component (A).
