PROBLEM TO BE SOLVED: To provide a conjugated diene polymer composition that is excellent in fuel economy.SOLUTION: Provided is a conjugated diene polymer composition containing the following polymer A, a silica, and a particular silane coupling agent B, and in which the content of silica is 5 pts.wt. or more to 150 pts.wt. per 100 pts.wt. of polymer A, and the content of silane coupling agent B is 0.5 pts.wt. or more and 20 pts.wt. or less per 100 pts.wt. of silica. Polymer A: a conjugated diene polymer obtained by polymerizing a conjugated diene, or co-polymerizing a conjugated diene and a comonomer, using an organo-alkali metal compound as a polymerization initiator, in a hydrocarbon solution containing at least one compound selected from the group consisting of limonene, terpinene and terpinolene.SELECTED DRAWING: None |
