摘要： An object of the present invention is to provide a method of producing a copolymer that produces an aromatic vinyl-diene copolymer having a low glass transition temperature, and a method of producing a rubber composition using the method. The subject method produces an aromatic vinyl-diene copolymer having a content of repeating units derived from an aromatic vinyl in an amount of 18 mass % or greater, and among repeating units derived from a diene, a proportion of a vinyl structure of 8 mol % or less, a proportion of a 1,4-trans structure of 60 mol % or less, and a proportion of a 1,4-cis structure from 40 to 95 mol %, the method including copolymerizing a monomer containing an aromatic vinyl and a diene using an initiator prepared with an organolithium compound, an alkylaluminum, a metal alcoholate, and at least one polar compound selected from the group consisting of water and an alcohol.

摘要： A rubber composition for tire tread contains a diene-based rubber including 30 wt % or more of a terminal modifying group-containing conjugated diene-based copolymer, silica, carbon black, and at least one of silane coupling agents represented by specified formulae. The total amount of silica and carbon black in the composition is 35 to 140 parts by weight relative to 100 parts by weight of the diene-based rubber, while the silane coupling agent content is 4 to 18 wt % on the silica content. The copolymer is produced by a specified method such that the aromatic vinyl monomer content in the copolymer is 38 to 48 wt %, the vinyl unit content in all the conjugated diene-based monomers is 20 to 35 mol %, the weight average molecular weight of the copolymer is 600,000 to 1,000,000, and the terminal modifying group in the copolymer contains a functional group which interacts with the silica.
