| description | To provide: a polymer composition which exhibits excellent cold flow resistance; a method for producing the same; a rubber composition containing the polymer composition; and a tire obtained using the rubber composition.SOLUTION: A polymer composition contains a diene-based polymer having a number average molecular weight of 500,000 g/mol or more, and a resin having a value of %H Ar of 20% or more and a softening point of 110°C or more. The content of the resin is 20 pts.mass or more relative to 100 pts.mass of the diene-based polymer.SELECTED DRAWING: None
【課題】耐コールドフロー性に優れるポリマー組成物及びその製造方法、並びに、該ポリマー組成物を含むゴム組成物、及び該ゴム組成物を用いたタイヤを提供する。【解決手段】数平均分子量が５００，０００ｇ／ｍｏｌ以上であるジエン系ポリマーと、％Ｈ Ａｒ値が２０％以上かつ軟化点が１１０℃以上の樹脂とを含有し、前記樹脂の含有量が、前記ジエン系ポリマー１００質量部に対し２０質量部以上であるポリマー組成物。【選択図】なし |
