Abstract
PURPOSE: A rubber composition having low vulcanization return, and well balanced processing characteristics, wear resistance, and wet skid resistance, obtained by blending a specific styrene-butadiene copolymer with a specified polybutadiene.
CONSTITUTION: (A) A styrene-butadiene copolymer having a styrene content of 10W60wt% and a vinyl bond amount of the butadiene part of 25W80wt% is blended with (B) a polybutadiene having a vinyl bond amount of 25W95wt% and (C) one or more rubber-like conjugated type polymers in such a way that a weight ratio of component A to component B is (20W80):(80W20), preferably (25W27):(75W25) and a weight ratio of component A+B to component C is (100W 25):(0W75). A blend of the component A and the component B having a styrene content of 10W50wt% and a vinyl bond amount of the butadiene part of 35W 80wt% is preferably used. Natural rubber or polyisoprene is preferable as the component C.
