Description
窒素置換された耐熱反応容器に、シクロヘキサンを2.5L、テトラヒドロフランを50g、n-ブチルリチウムを0.12g、スチレンを100g、1,3−ブタジエンを400g入れ、反応温度50℃で重合を行った。重合が完了した後にN,N−ビス(トリメチルシリル)アミノプロピルメチルジエトキシランを1.7g加えて、1時間反応させた後、水素ガスを0.4MPa−ゲージの圧力で供給し、20分間撹拌し反応させ、ポリマー末端を水素化リチウムとした。次いで、水素ガス供給圧力を0.7MPa−ゲージ、反応温度を90℃とし、チタノセンジクロリドを主とした触媒を用いて目的の水素添加率となるまで反応させ、溶媒を除去することにより、水添共重合体1を得た。
水素添加を行う反応時間を変更し、目的の水素添加率を変更した以外、合成例1と同様の方法によって水添共重合体2を得た。得られた水添共重合体2の重量平均分子量は標準ポリスチレンによるポリスチレン換算で35万、結合スチレン量20質量%であり、ブタジエン部の水素添加率は80モル%であった。
バンバリーミキサーを使用し、下記表1に示す配合(質量部)に従い、まず、第一混合段階(ノンプロ練り工程)で、加硫促進剤、及び硫黄を除く成分を添加混合し(排出温度=160℃)、次いで、得られた混合物に、最終混合段階(プロ練り工程)で、加硫促進剤及び硫黄を添加混合して(排出温度=90℃)、ゴム組成物を調製した。
