Abstract
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、結合スチレン量は20質量%、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。
・水添SBR1:上記合成例1に従い作製した水添共重合体1
・水添SBR2:上記合成例2に従い作製した水添共重合体2
・SBR:JSR(株)製「SBR0122」、スチレンとブタジエン部中のビニル基の質量比(スチレン/ブタジエン部中のビニル基)=37/14
・シリカ:エボニック社製「UltrasilVN3」
・カーボンブラック:東海カーボン(株)製「シースト3」
・オイル:JXエネルギー(株)製「プロセスNC140」
・樹脂1:クマロンインデン樹脂、Rutgers Chemicals社製「NOVARES C30」、軟化点=20〜30℃
・樹脂2:C5/C9系樹脂、東邦化学工業(株)製「トーホーハイレジン」、軟化点=95〜103℃
・樹脂3:フェノール系樹脂、(株)日本触媒製「SP1068」、軟化点=82〜100℃
・樹脂4:ロジン系樹脂、ハリマ化成(株)製「ハリマックT−90」、軟化点=80〜90℃
・樹脂5:テルペン系樹脂、アリゾナケミカル(株)製「TP115」、軟化点=115℃
・亜鉛華:三井金属鉱業(株)製「亜鉛華3号」
・ステアリン酸:花王(株)製「ルナックS−20」
・老化防止剤:大内新興化学工業(株)製「ノクラック6C」
・ワックス:日本精蝋(株)製「OZOACE0355」
・シランカップリング剤:エボニック社製「Si69」
・硫黄:鶴見化学工業(株)製「粉末硫黄」
・加硫促進剤1:大内新興化学工業(株)製「ノクセラ−D」
・加硫促進剤2:住友化学(株)製「ソクシノールCZ」
さらに比較例1と比較例4との対比からは、水添SBRの一部をスチレンの含有割合が高いSBRに置換すると、破断強度が低下することが分かる。
