  "textContent": "Provided is a polymer composition that has satisfactory processability, and is suited for the production of a tire highly well balanced among impact resilience, wet grip property, low loss property, and tensile strength. The polymer composition according to the invention contains: (A) a conjugated diene-based polymer that is a reaction product between a polymer having an active polymerization end, which is obtained by polymerizing a conjugated diene compound, or a conjugated diene compound and an aromatic vinyl compound, in the presence of an alkali metal compound or an alkaline earth metal compound, and a compound represented by any one of the general formulae (1) to (3); and (B) conjugated diene-based polymer particles.",
