Provided is a polymer composition which has good processability and is suitable for the production of a tire having an excellent balance among resilience, wet grip, low loss, and tensile strength. This polymer composition contains: (A) a conjugated diene polymer which is a reaction product of a polymer having a living polymerization terminal and a compound represented by any one of general formulae (1)-(3); the polymer having a living polymerization terminal is obtained by polymerizing a conjugated diene compound or a conjugated diene compound with an aromatic vinyl compound in the presence of an alkali metal compound or an alkaline earth metal compound; and (B) conjugated diene polymer particles.

    本发明提供一种加工性良好,适合于回弹性、湿地抓地性、低损耗性、及拉伸强度高度平衡优异的轮胎的制造的聚合物组合物。本发明的聚合物组合物包含:(A)共轭二烯系聚合物,是具有活性聚合末端的聚合物与通式(1)~(3)中任一个表示的化合物的反应产物,所述具有活性聚合末端的聚合物在碱金属化合物或碱土类金属化合物的存在下使共轭二烯化合物或共轭二烯化合物与芳香族乙烯基化合物聚合而获得;以及(B)共轭二烯系聚合物粒子。
