Abstract
PURPOSE: A vulcanized rubber composition suitably used for tire tread that is made by vulcanizing a mixture of a rubber and a polymer having a specific range of glass transition point respectively, thus having a small friction coefficient and large wet-skid resistance.
CONSTITUTION: The vulcanization of a mixture consisting of 90W50pts.wt. of a rubber of -120W-40°C glass transition point (Tg) and 10W50 parts of a polymer of 0°C or higher Tg or a block or graft copolymer consisting of 50W80wt% of the rubber part of -120W-40°C Tg and 50W20wt% of the polymer part of 0°C or higher Tg gives said vulcanized rubber composition that has a mechanical loss tangent larger in 1sec-1 angular frequency than in 105 sec-1 and the minimum value larger than 0.05 in the range of 1W105 sec-1 reduced angular frequency of vibration force at 25°C.
EFFECT: The fuel-milage and safety of cars can be increased.
