PROBLEM TO BE SOLVED: To provide a master batch capable of improving fatigue property of a rubber composition.SOLUTION: There is provided a master batch by mixing 100 pts.mass of a halogenated stellate branched butyl rubber and 20 to 100 pts.mass of a thiazole-based vulcanization accelerator. There is also provided a rubber composition by mixing a rubber component containing a butyl rubber with the master batch and having content of the thiazole-based vulcanization accelerator of 0.1 to 10 pts.mass based on 100 pts.mass of total rubber component containing the halogenated stellate branched butyl rubber contained in the master batch. There is also provided a pneumatic tire having an inner liner consisting of the rubber composition.SELECTED DRAWING: None

    【課題】ゴム組成物の疲労性を改善することができるマスターバッチを提供する。【解決手段】ハロゲン化星状分岐ブチルゴム100質量部とチアゾール系加硫促進剤20〜100質量部とを混合してなるマスターバッチである。また、ブチル系ゴムを含むゴム成分に該マスターバッチを混合してなり、前記マスターバッチに含まれるハロゲン化星状分岐ブチルゴムを含む全ゴム成分100質量部に対する前記チアゾール系加硫促進剤の含有量が0.1〜10質量部であるゴム組成物である。また、該ゴム組成物からなるインナーライナーを備えた空気入りタイヤである。【選択図】なし
