Abstract: A styrene-butadiene copolymer having excellent low hysteresis loss characteristic, wet skid resistance, fracture characteristics, and abrasion resistance and a rubber composition comprising the copolymer are provided. The styrene-butadiene copolymer has a total styrene content in the range of 33 to 42 % by weight of the styrene-butadiene copolymer; a content of styrene sequences having 4 to 20 styrene units in the range of 40 to 65 % by weight of the total styrene content, as obtained by measurements by NMR and GPC; a content of styrene sequences having more than 20 styrene units in the range of 5 % by weight or less of the total styrene content, as obtained by measurement by GPC; a content of vinyl unit in the range of 30 % by mol or less of a butadiene part of the styrene-butadiene copolymer; a sum of the total styrene value and 1/2 of the content of vinyl units in the range of 46 to 52 %; and an inner or end structure having, for example, tin-carbon bond. The copolymer and the rubber composition are used for tire treads and the like.

Abstract: In a polymerization process of at least one of monomers selected from the group consisting of conjugated diene compounds such as butadiene and vinylaromatic compounds such as styrene, an organolithium compound such as butyllithium is added to the polymerization system first in the presence of the monomer, and thereafter a secondary amine compound such as saturated cyclic imine is added thereto to produce a soluble initiator by bringing the both compound into contact with each other. Polymerization is carried out with the soluble initiator formed. The obtained high molecular weight polymer is modified with a coupling agent such as tin tetrachloride. The polymer obtained has a high molecular weight, a narrow molecular weight distribution, and controlled molecular weight, and exhibits remarkable coupling property, low hysteresis loss. The process provides a polymer having a consistent characteristic, regardless of production scale and procedures of adding materials.

Further, the invention contemplates a polymer, a polymer composition and products therefrom, which include a functional group from the reaction product of an amine and an organolithium compound. The resulting polymers may be terminated with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.
