Abstract:
A rubber composition having improved tensile modulus and improved abrasion resistance comprising 100 parts by weight of a diene rubber, 10 to 120 parts by weight of silica, 0.1 to 15 parts by weight of a vulcanizer and 0.1 to 15 parts by weight of a vulcanization accelerator, wherein the diene rubber is (A) an amino group-containing diene rubber having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) Of 20 to 250 or a mixture of said amino group-containing diene rubber (A) with other diene rubber (B), the silica has a nitrogen adsorption specific surface area of 100 to 250 m.sup.2 /g as measured by the BET method, and further the vulcanization accelerator is a sulfonamide compound.
