ポリマーA
分子量258,000のポリスチレン−ポリブタジエン−ポリスチレン(SBS)ブロックコポリマー30lバッチを、sec−ブチルリチウムを開始剤として用いて、逐次アニオン重合によってステンレス鋼製反応器中で調製した。重合はシクロヘキサン中で行い、150ppmのジエトキシプロパンを加えた。重合の終わりに、リビングSBS−Liポリマーを1当量の2−エチル−1−ヘキサノールで停止し、ポリマー(SBS)とリチウム2−エチル−1−ヘキサンオキシドを含むポリマー溶液を製造した。ポリマー溶液は10.4重量%のポリマーを含んだ。SBSポリマーのスチレン含有量は30重量%であり、中間ブロックのビニル含有量は40モル%である。
ポリマーAの工程を用いて、低分子量のポリマーBを含むポリマー溶液を作製した。分子量は110,000であった。ポリマー溶液は12.9重量%のポリマーBを含んだ。
重合の停止に2−エチル−1−ヘキサノールの代わりに水素を使用すること以外はポリマーBと同様にして、水素末端ポリマーCを作製した。
触媒は、1000〜1500ppm(百万分の1部)の濃度のNi、Co(比較例)、またはFeを有する溶液として調製した。触媒は、ニッケルオクタノアート、コバルトネオデカノアート、または鉄2−エチル−1−へキサノアートを用い、Ni、Co又はFeカルボキシラートをシクロヘキサン中に希釈することによって調製し、次いでトリエチルアルミニウムをゆっくり加えてモル比3.0/lのAl/M(M=Ni、Co、またはFe)を得た。
ステンレス鋼製反応器に、上述のようにして調製した800gのSBSポリマー溶液を装填した。反応器の温度は一定に保った。ニッケル、コバルト、鉄含有触媒の触媒懸濁物を反応器に加え、水素圧力を40バールに上昇させた。直ちに発熱反応が開始した、水素化を数時間行い、その間にサンプルを反応器から引き抜いて1H−NMRによって分析し、オレフィン性二重結合の変換を測定した。
ポリマーAのSBS溶液をポリマー溶液中1ppmのNiまたはCo触媒を用いて水素化した。反応器の温度を40℃で一定に保った。結果を表1に示す。
ポリマーAのSBS溶液をポリマー溶液中5ppmのFe触媒を用いて水素化した。反応器の温度を70℃で一定に保った。結果を表1に示す。
ポリマーBのSBS溶液をポリマー溶液中5ppmのFe触媒を用いて水素化した。反応器の温度を60℃で一定に保った。結果を表2に示す。
反応器にポリマーCを装填した。2−エチル−1−ヘキサノールを加えてLiHの66%をリチウムアルコキシドに変換した。水素化は実施例4のように実施した。結果を表2に示す。
反応器にポリマーCを装填した。2−エチル−1−ヘキサノールを加えてLiHの45%をリチウムアルコキシドに変換した。水素化は実施例4のように実施した。結果を表2に示す。
反応器にポリマーCを装填した。水素化は実施例4のように実施した。結果を表2に示す。
反応器にポリマーCを装填した。SBSポリマー溶液をポリマー溶液中1ppmのFe触媒を用いて水素化した。反応器の温度を60℃で一定に保った。結果を表2に示す。
ポリマーD
ポリマーDは、スチレン含有量約25重量%、分子量315,000、ビニル含有量約60%、カプリング効率約67%(カプリング剤としてアジピン酸ジエチルを用いて)の分岐SBS型ポリマーである。ポリマー溶液はシクロヘキサン中約9重量%のポリマーを含んだ。ポリマーはポリマー溶液中20ppmのFe触媒を用いて部分的に選択的に水素化した。水素化の後、ポリマーのビニル含有量は約5%であり、1,4−二重結合含有量は約30%である。ポリマー溶液は水素化の後窒素雰囲気に維持した。
抽出は、窒素で完全にパージした3リットルのガラス容器中75℃で行った。容器に0.8リットルの酸(水中の0.5重量%H2SO4)を加えた。溶液を通して30分間窒素を泡立てて酸素を追い出した。0.8kgのポリマー溶液Dを激しく攪拌(1200rpm)しながら容器に加えた。混合物を通して1分間空気を泡立てた。抽出中の圧力は0.2MPa未満に維持した。60分後、混合を停止し、内容物を20分間相分離させた。水性相を抽出容器から完全に排出した。次いでポリマー溶液のサンプルを採取した。サンプルを遠心分離して水を除去した。ポリマー中の鉄は誘導結合プラズマ/質量分光計(ICP/MS)によって求めた。結果を表4に示す。
実施例9を繰り返した。しかし、この実験では希釈酸とポリマー溶液の混合物を通す空気の泡立ては行わなかった。再び、結果を表4に示す。
実施例9のポリマー溶液に400ppmのネオデカン酸を加えた。金属は上述の工程にしたがって除去した。結果を表4に示す。
実施例10と同様に、ポリマー溶液に400ppmのネオデカン酸を加えた。この実験では、希釈酸とポリマー溶液の混合物を通す空気の泡立ては行わなかった。結果を表4に示す。
