CONJUGATED DIENE POLYMER, METHOD FOR PRODUCING THE SAME, AND CONJUGATED DIENE POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a conjugated diene polymer which is excellent in affinity with carbon black and in balance between wet skid characteristics and low hysteresis loss properties when vulcanized, and satisfies abrasion resistance and breaking strength sufficient for practical applications.

SOLUTION: The conjugated diene polymer is obtained by polymerizing a conjugated diene compound or copolymerizing the conjugated diene compound with an aromatic vinyl compound while using an anionic polymerization initiator prepared by reacting a polyvinyl aromatic compound with an amidolithium compound at a molar ratio (polyvinyl aromatic compound/amidolithium compound) of ≥0.01 and <0.4.
