摘要：
Disclosed are a conjugated polyene copolymer comprising a random copolymer having structural units derived from α-olefin (A1) of 2 to 20 carbon atoms and structural units derived from nonconjugated polyene (A2), said nonconjugated polyene copolymer having a glass transition temperature (Tg) of −25 to 20 □ and Mooney viscosity of [ML(1+4)100□] of 5 to 190; a rubber composition comprising the nonconjugated polyene copolymer and a diene-based rubber (B); a modifier for tires comprising the copolymer; a rubber material for tires comprising the rubber composition; a tire tread obtained from the rubber material for tires; and a tire having the tire tread.
