Document Type and Number:
WIPO Patent Application WO/2005/085343
Kind Code:
A1
Abstract:
Disclosed is a rubber composition which is excellent in processability of the unvulcanized compounded rubber as well as wear resistance and wet skid resistance of the vulcanized rubber, while having low rolling resistance. The rubber composition is useful for tire applications, in particular it is useful for tire treads giving weight to low fuel consumption and safety. The rubber composition mainly contains (I) 0.5-35 weight% of a conjugated diene (co)polymer rubber having an amino group and an alkoxysilyl group in the polymer chain with a weight average molecular weight of 1,000-90,000, and (II) 99.5-65 weight% of a conjugated diene (co)polymer rubber other than the component (I) having a weight average molecular weight of 100,000-2,000,000 (while satisfying (I) + (II) = 100 weight%).
