The invention provides a polymer composition which has not only excellent low loss properties and wet gripping properties but also excellent high-level balance in terms of mechanical strength, tensile strength, and steering stability, and which is suitable for manufacturing a tire. A polymer composition according to the present invention contains: (A) a conjugated diene-based polymer which is a polymer of a conjugated diene compound or a copolymer of a conjugated diene compound and an aromatic vinyl compound, and is a reaction product of an active polymer terminal and a compound represented by any one of general formulae (1)-(4); and (B) an organic short fiber.

    本发明提供一种不仅低损耗性及湿地抓地性优异,而且在机械强度、拉伸强度及操纵稳定性方面也高度平衡优异的适合于轮胎的制造的聚合物组合物。本发明的聚合物组合物含有:(A)共轭二烯系聚合物,其为共轭二烯化合物的聚合物或者共轭二烯化合物与芳香族乙烯基化合物的共聚物,且为活性聚合末端与通式(1)~通式(4)中的任一者所表示的化合物的反应产物;以及(B)有机短纤维。
