To provide a tire tread composition comprising a dicyclopentadiene (DCPD)-based resin functionalized with groups capable of reacting with silica or carbon black, where the composition exhibits enhanced durability, traction, handling and extractability properties.SOLUTION: A functionalized resin is obtained by contacting a polymer comprising units derived from (DCPD) with a vinyl monomer or vinylene monomer in the presence of a metathesis catalyst, where the vinyl monomer or vinylene monomer comprises a reaction product comprising at least one of silyl, siloxy and alkoxysilyl groups.SELECTED DRAWING: Figure 1 【課題】耐久性、牽引特性、ハンドリング性、および抽出性特性の増強を示す、シリカまたはカーボンブラックと反応可能な基で官能化されたジシクロペンタジエン（ＤＣＰＤ）ベース樹脂を含むタイヤトレッド組成物の提供。【解決手段】（ＤＣＰＤ）に由来する単位を含むポリマーとシリル基、シロキシ基、またはアルコキシシリル基のうちの少なくとも１つを含む、反応生成物を含むビニルモノマーまたはビニレンモノマーとをメタセシス触媒の存在下で接触させることにより得られる官能化樹脂の提供。【選択図】図１
