十分に乾燥した400ml耐圧ガラス反応器に、1,3-ブタジエン13.58g(0.25mol)を含むトルエン溶液325mlを添加した後、エチレンを0.4MPaで30分間導入した。エチレンの導入後、重合反応系の重量は7.00g増加しており、該重合反応系内にエチレンが0.25mol導入されていることを確認した。よって、重合開始時におけるエチレン濃度Eのブタジエン濃度Bdに対する比(E/Bd)は1.00である。一方、窒素雰囲気下のグローブボックス中で、ガラス製容器にビス(2-フェニルインデニル)ガドリニウムビス(ジメチルシリルアミド)[(2-PhC9H6)2GdN(SiHMe2)2]18μmol、ジメチルアニリニウムテトラキス(ペンタフルオロフェニル)ボレート[Me2NHPhB(C6F5)4]36μmol、及びジイソブチルアルミニウムハイドライド0.90mmolを仕込み、トルエン10mlに溶解させて触媒溶液とした。その後、グローブボックスから触媒溶液を取り出し、ガドリニウム換算で17.5μmolとなる量の触媒溶液をモノマー溶液へ添加し、室温で180分間重合を行った。重合後、2,2'-メチレン-ビス(4-エチル-6-t-ブチルフェノール)(NS−5)5質量%のイソプロパノール溶液1mlを加えて反応を停止させ、さらに大量のメタノールで共重合体を分離し、70℃で真空乾燥し、共重合体Aを得た。得られた共重合体Aの収量は12.00gであった。
エチレンを0.8MPaで30分間導入し、エチレンを12.5g(0.45mol)仕込む(E/Bd=1.80)こと以外は、上記実施例1と同様にして重合を行ったところ、収量10.30gで共重合体Bを得た。
ジイソブチルアルミニウムハイドライドの仕込み量を1.35mmolに変更した以外は、上記実施例1と同様にして重合を行ったところ、収量13.65gで共重合体Cを得た。
十分に乾燥した200ml耐圧ガラス反応器に、1,3-ブタジエン3.38g(0.063mol)を含むトルエン溶液20mlを添加した後、エチレンを2.45g(0.088mol)導入した(E/Bd=1.40)。一方、窒素雰囲気下のグローブボックス中で、ガラス製容器にビス(2-フェニルインデニル)ガドリニウムビス(ジメチルシリルアミド)[(2-PhC9H6)2GdN(SiHMe2)2]5.5μmol、ジメチルアニリニウムテトラキス(ペンタフルオロフェニル)ボレート[Me2NHPhB(C6F5)4]11.0μmol、及びトリイソブチルアルミニウム0.41mmolを仕込み、トルエン10mlに溶解させて触媒溶液とした。その後、グローブボックスから触媒溶液を取り出し、ガドリニウム換算で5.0μmolとなる量の触媒溶液をモノマー溶液へ添加し、室温で240分間重合を行った。重合後、2,2'-メチレン-ビス(4-エチル-6-t-ブチルフェノール)(NS−5)5質量%のイソプロパノール溶液1mlを加えて反応を停止させ、さらに大量のメタノールで共重合体を分離し、70℃で真空乾燥し、共重合体Dを得た。得られた共重合体Dの収量は4.15gであった。
乾燥及び窒素置換された1Lのゴム栓付きガラス瓶に、1,3-ブタジエン54g(1mol)を含むトルエン溶液450gを添加し、モノマー溶液とした。一方、窒素雰囲気下のグローブボックス中で、ガラス製容器にビス(2-フェニルインデニル)ガドリニウムビス(ジメチルシリルアミド)[(2-PhC9H6)2GdN(SiHMe2)2]3μmol、ジメチルアニリニウムテトラキス(ペンタフルオロフェニル)ボレート[Me2NHPhB(C6F5)4]4.5μmol、及びジイソブチルアルミニウムハイドライド1.5mmolを仕込み、トルエン5mlに溶解させて触媒溶液とした。その後、グローブボックスから触媒溶液を取り出し、ガドリニウム換算で2μmolとなる量の触媒溶液をモノマー溶液へ添加し、室温で180分間重合を行った。重合後、2,2'-メチレン-ビス(4-エチル-6-t-ブチルフェノール)(NS−5)5質量%のイソプロパノール溶液2mlを加えて反応を停止させ、さらに大量のメタノールで共重合体を分離し、70℃で真空乾燥したところ、収量54gでポリブタジエンEを得た。
