エチレン反応時間を3分からそれぞれ5分(実施例2)、7分(実施例3)、及び9分(実施例4)に変えたことを除いては、実施例1と同じ方法で行った。
トリオクチルアルミニウム(12mg,33μmol)の代わりに、MMAO(modified methylaluminoxane,12.7mg,7.0w%-Al,33μmol)を使用し、エチレン反応時間を3分から7分に変えたことを除いては、実施例1と同じ方法で行った。
実施例1の第1段階を省略し、チーグラー-ナッタ触媒のリビング(living)重合性質を利用してTiCl3-Et2AlCl触媒システムに連続的にエチレン-エチレン/プロピレン混合ガス/エチレン(比較例5)及びプロピレン-エチレン/プロピレン混合ガス/プロピレン(比較例6)をそれぞれ投入して、共重合体であるポリエチレン-block-ポリ(エチレン-co-プロピレン)-block-ポリエチレン(比較例7)又はポリプロピレン-block-ポリ(エチレン-co-プロピレン)-block-ポリプロピレン)(比較例8)の重合体を製造した。具体的な実験方法は、非特許文献5の提示と同様に行った。
(1)GPCデータ
高分子を3000ppmの濃度で1,2,4-トリクロロベンゼンに溶解させてGPC機械に投入し、2,4-ジtert-ブチル-4-メチルフェノール(0.04%)を酸化安定剤として含む1,2,4-トリクロロベンゼンを160℃で1.0mL/minの流速で流してデータを得、PS標準を基準にした検量曲線から分子量を計算した。
溶融温度(Tm)を15℃/minの加熱速度でDSC機械によって測定した。
ポリマーのサンプルは、135℃の二つのホットプレートの間で5MPaの圧力で20分間維持した後、10MPaの圧力で100分間圧力を維持しながら圧縮させた。厚さが1mmの得られたポリマーフィルムを4つの欠片(100×10mm2の大きさ)に切断した。引張試験は、ASTM D882に従って温度25(±2)℃及び湿度45(±5)%で50mmのゲージ長さで500mm/分の引抜速度でUTM(WL2100)を使用して各配置に対して二回ずつ行った。各試験片は、引張試験で測定された破断点距離の半分まで10サイクル以上引張した。
(1)GPCデータ
図1は、実施例1で製造された高分子のラウロイルパーオキサイド(CH3(CH2)10C(O)O-OC(O)(CH2)10CH3)投入前(a)及び後(b)のGPC分析グラフを示したものである。ラウロイルパーオキサイド(CH3(CH2)10C(O)O-OC(O)(CH2)10CH3)を投入することによって、Mn値が1.75倍増加したことが確認できた。その他の実施例でもラウロイルパーオキサイド(CH3(CH2)10C(O)O-OC(O)(CH2)10CH3)処理することによってMn値が1.5倍~2倍増加することを確認してラウロイルパーオキサイドを反応させることにより、実験例で観察したC(sp3)-C(sp3)結合形成反応が行われて化学式1の対称型ポリオレフィンブロック共重合体が形成されたことが分かる。
図2は、実施例1で製造されたポリエチレン-block-ポリ(エチレン-co-プロピレン)-block-ポリエチレントリブロック共重合体のDSC分析結果を表したものである。図2を参照すると、124℃付近でポリエチレンブロックのTmシグナルを観察することができ、0℃~60℃間でポリ(エチレン-co-プロピレン)ブロックのTmを弱く観察できた。
図3は、実施例1で製造したポリエチレン-block-ポリ(エチレン-co-プロピレン)-block-ポリエチレントリブロック共重合体の反復引張試験の結果を表すものであり、製造したトリブロック共重合体がエラストマー性質があることを表す結果を確認した。
