Abstract:
A diene rubber composition comprising 100 parts by weight of a diene rubber component composed of 10-100 wt. % of an amino group-containing diene copolymer rubber (A) having a composition (based on the bound amount) of 40-99.95 wt. % of a conjugated diene monomer, 0.05-20 wt. % of an amino group-containing vinyl monomer and 0-55% wt. % of an aromatic vinyl monomer and having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 30-150, and 0-90 wt. % of another diene rubber (B), 10-150 parts by weight of silica having a specific surface area of 50-220 m.sup.2 /g as determined by nitrogen absorption (BET method), and a silane coupling agent in a proportion of 2-10 parts by weight per 100 parts by weight of the silica.
