To provide a coupling agent for improving dispersibility of carbon black as a filler in a rubber composition for a tire, especially for preparing a tire tread.SOLUTION: A rubber composition contains a coupling agent represented by the general formula in the figure that may induce interactions between an ingredient rubber and carbon black, thereby capable of improving dispersibility of the carbon black in the rubber composition and realizing a tire with low rolling-resistance properties and excellent wear resistance.SELECTED DRAWING: None 【課題】タイヤ用、特に、タイヤトレッドを製造するためのゴム組成物のうち、充填剤としてカーボンブラックの分散性を向上させるためのカップリング剤を提供する。【解決手段】ゴム組成物は、原料ゴムとカーボンブラックの間の相互作用を誘導できる、下記一般式で表されるカップリング剤を含ませることにより、ゴム組成物のうちカーボンブラックの分散性を向上させ、低い転がり抵抗の特性及び優れた耐磨耗性を有するタイヤを具現することができる。【選択図】なし
