Rieger et al(Rieger B., Troll C., and Preuschen J., in Macromolecules 2002,35,5742-5743)
本発明の別の目的は、高分子量成分が改良されたポリオレフィンを提供することにある。
本発明のさらに別の目的は、機械特性が改良されたポリオレフィンを製造するためのハフニウムベースのメタロセン触媒成分の使用にある。
(a)ハフニウムベースの触媒成分、
(b)アルミノキサンと立体障害ルイス塩基とを含む配位能力が低いか、全くない活性化剤。
活性化剤としてアルミノキサンを用いた時には若干のアルミニウムアルキルが常に同時に存在することは避けられない。驚くべきことに、本発明者はこのアルミニウムアルキルがハフニウムベースのメタロセン触媒系の低活性に関与しているということを同定した。従って、このアルミニウムアルキルを活性カチオン化学種を損なわない化学剤で捕捉する方法を提供することが本発明の目的である。そうした化学剤は立体障害ルイス塩基である。
R’’(CpRn)(FluR’m)Hf Q2 (I)
(ここで、
Cpはシクロペンタジエニル環であり、
Fluはフルオレニル環であり、
各Rは水素または1〜20個の炭素原子を有するヒドロカルビル基、例えばアルキル、アルケニル、アリール、アルキルアリールまたは、アリールアルキル基であり、互いに同一でも異なっていてもよく、また、2つの炭素原子が互いに結合してC4〜C6環を形成していてもよく、
各R’は水素または1〜20個の炭素原子を有するヒドロカルビル基、例えばアルキル、アルケニル、アリール、アルキルアリールまたはアリールアルキル基であり、互いに同一でも異なっていてもよく、
R’’は2つのCp環の間のブリッジ構造であり、
Qは1〜20個の炭素原子を有するヒドロカルビル基、例えばアリール、アルキル、アルケニル、アルキルアリールまたはアリールアルキル基、1〜20個の炭素原子を有するヒドロカルボキシ基またはハロゲンであり、互いに同一でも異なっていてもよく、
nは0〜4の整数、mは0〜8の整数である)
本発明の触媒成分中のリガンド間に存在するブリッジの型は特に限定されていない。一般に、R’’は1〜20個の炭素原子を有するアルキリデン基、ゲルマニウム基(例えばジアルキルゲルマニウム基)、シリコン基(例えばジアルキルシリコン基)、シロキサン基(ジアルキルシロキサン基)、アルキルホスフィン基またはアミン基から成る。ブリッジ構造上の置換基は少なくとも一つの炭素を有するヒドロカルビル基、例えば置換または未置換のエチレニル基、例えば−CH2−CH2−(Et)を含むのが好ましい。R’’はPh2C、EtまたはMe2Siであるのがさらに好ましい。
リガンド上に存在する一つまたは複数の置換基は特に限定されていない。2つ以上の置換基が存在する場合は互いに同一でも異なっていてもよい。一般に、これらは互いに独立して、1〜20個の炭素原子を有するヒドロカルビル基の中から選択される。
R’’(FluR’m)X Hf Q2 (II)
(ここで、R’’、Cp、R’およびQは上記定義のもの、Xは第15族または第16族の中から選択され1つまたは2つの孤立対電子を有するヘテロ原子リガンド、Xは窒素、燐、酸素または硫黄で、置換されていてもよい)
Cs対称性が望まれる場合には、シクロペンタジエニル基とフルオレニル基の両方が未置換であるのが好ましい。
C1対称性が望まれる場合には、シクロペンタジエニル上の好ましい置換基は、ブリッジの頭部の基端位置であり、3位置にあるメチルまたはtert-ブチルであるのがさらに好ましい。フルオレニルは未置換であるのが好ましい。
本発明で使用するのに適した化合物はN,N−ジメチルアニリン、エチルアミン、ジエチルアミン、トリエチルアミン、トリフェニルアミン、トリフェニルホスフィン、ヘキサメチルリン酸トリアミド、ジエチルエーテル、エタノール、フェノール、チオフェノール、2,6−ジ−t−ブチル−4−メチルフェノール、テトラエトキシシラン、フェニルトリエトキシシラン、ジフェニルジエトキシシラン、トリフェニルエトキシシラン、ジエチルジエトキシシランである。
アルミノキサンとルイス塩基とを混合し、平衡に達するように30分〜2時間、好ましくは約1時間反応させる。
添加するアルミノキサンの量はAl/Hf比が100〜5000、好ましくは500〜2000になるようにする。
本発明のハフノセンベース触媒系の生産性は少なくとも20倍高くなる。
A.ハフニウムベースの触媒成分を含む触媒系、アルミノキサンと立体障害ルイス塩基とを含む活性化剤および任意成分の担体を用意し、
B.この触媒系をオレフィンモノマーと任意成分のコモノマーとを入れた重合帯域に導入し、
C.反応帯域を重合条件下に維持し、
D.所望のポリオレフィンを抜き出す。
担体は表面積が200〜700m2/gで、細孔容積が0.5〜3ml/gであるシリカ担体であるのが好ましい。
変形例ではフッ素化活性担体を用いることもできる。
好ましい溶剤には鉱油および反応温度で液体であり且つ個々の成分と反応しない種々の炭化水素がある。有用な溶剤の例としてはペンタン、イソペンタン、ヘキサン、ヘプタン、オクタンおよびノナンのようなアルカン、シクロペンタン、シクロヘキサンのようなシクロアルカンおよびベンゼン、トルエン、エチルベンゼンおよびジエチルベンゼンのような芳香族化合物が挙げられる。
担体材料はトルエンでスラリー化し、触媒成分および活性化剤は担体材料に添加する前にトルエンに溶かすのが好ましい。
必要に応じてさらに予備重合を行うことができる。
αオレフィンはプロピレンであるのが好ましい。
金属MとしてはそれぞれZrおよびHfを選択した。全ての重合反応は50℃の温度で、トルエンで調製したC3H6の0.4M溶液を用いて行った。活性化剤はそれぞれメチルアミノキサン(MAO)またはMAO/フェノール混合物にした。活性化剤としてMAOを用いたときは[Al]/[M]比を1.103にし、活性化剤としてMAO/フェノール混合物を用いたときは[Al]/[M]比を(1.0〜1.5).103にし、[フェノール]/[Al]比は0.6にした(ここで[Al]はアルミニウムの総量である)。結果は[表1]に示してある。
この結果にはkgPP/{[C3H6]*molHf *h}で表される生産性、σで表される活性サイトエナンチオ選択性、スキップされた挿入の小数存在率Pskおよびテトラリン中で135℃で求めた粘度平均分子量Mvのポリマー特性が含まれる。
最初の重合は金属Mとしてハフニウムを選択し、シクロペンタジエニル上の置換基Rとしてメチルおよびtert-ブチルを選択して行った。全ての重合反応は50℃の温度で、トルエンで調製したプロペンの0.4M溶液を用いて行った。活性化剤としてMAOを用いたときは[Al]/[M]比を7.102とし、活性化剤としてMAO/フェノール混合物を用いたときは[Al]/[M]比を6.102とし、[フェノール]/[Al]比は0.6とした。結果は[表2]に示してある。
理論に拘束されるものではないが、この挙動は成長鎖エピマー化の結果である可能性がある。
