Abstract
Description
下記文献にはメタロセン触媒または触媒系を用いて一種以上のオレフィンを連続スラリーまたは気相重合法で重合する連続方法が記載されている。
下記文献には、担持メタロセン触媒と、アルミノキサンアクティベータと、トリイソブチルアルミニウムとを用いて、エチレンおよび任意成分のコモノマーを重合する方法が記載されている。
本発明の他の目的は、エチレンを高い生産性で重合する方法を提供することにある。
上記目的の少なくとも一つは本発明によって少なくとも部分的に達成できる。
本発明では反応装置の上記シーティングを反応装置の壁の熱伝導性を測定することで評価した。反応装置壁上のシーティングが増加すると熱伝導性は低下する。
本発明者は、従来技術の上記問題を少なくとも部分的に解決した、ポリエチレンの製造方法を見出した。
導入するスカベンジャの量は全希釈剤および反応物1トンの当りのグラム数で表すこともできる。この場合には、スカベンジャは希釈剤および存在する反応物1トン当り5g〜40gの量で導入される。いずれの表現でも、反応装置に供給した希釈剤および反応物中にスカベンジャを5〜40ppm(またはg/トン)導入することで連続法で最も簡単に達成できる。 スカベンジャは希釈剤および存在する反応物の総量に基づいて5、10または15g/トンから20、25、30、35または40g/トンまでの量を導入するのが好ましい。
R(C5R’k)2MQZ-2
(ここで、(C5R’k)はシクロペンタジエニルまたは置換したシクロペンタジエニルを表し、各R’は水素またはヒドロカルビル、例えば1〜20の炭素原子を有するアルキル、アルケニル、アリールまたはアリールアルキル基であり、2つの炭素原子が一緒になってC4〜C6環を形成することができ、互いに同じでも異なっていてもよく、Rは上記定義の2つの(C5R’k)をブリッジする、置換または未置換のC1〜C4アルキリデン基、ジアルキルゲルマニウムまたはジアルキルシリコンまたはジ−アロキシ(aloxy)シランまたはアルキルフォスフィンまたはアミン基であり、Qはヒドロカルビル基、例えば1〜20の炭素原子を有するアリール、アルキル、アルケニル、アルキルアリール基またはアリールアルキル基、1〜20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、互いに同じでも異なっていてもよく、Zは遷移金属の結合価であり、MはIVb、VbまたはVIb族遷移金属である)
メタロセン触媒は活性化すことができ、公知の任意の方法で支持できる。
本発明のエチレンの重合はスラリー相で行う。このスラリー法では一般に液体の重合希釈剤中にポリマーの固体粒子を懸濁させる工程が含まれる。使用する希釈剤は重合条件下で液体で且つ不活発でなければならない。一般的な重合希釈剤は4〜7の炭素原子を有する炭化水素、例えばイソブタンまたはヘキサンを含む。イソブタンを使うのが好ましい。
第2反応装置に追加するスカベンジャの量は第2反応装置に導入した追加の反応物と追加の希釈剤とを基にして重量で5、10または15ppmから20、25、30、35または40ppmまでの範囲にするのが好ましい。本発明方法の任意の時間での、希釈剤と存在する反応物との総量をベースにしたスカベンジャの量は5〜40ppmの間にある。これは各反応装置に供給される反応物および希釈剤の5〜40ppmのスカベンジャを導入することで連続法で最も簡単に得られる。
スカベンジャを中和する場合のスカベンジャに対する水のモル比は3、10、20、30から50、60、100、150または300である。
エチレン、ヘキセン、水素、トリイソブチルアルミニウム(TIBAL)、イソブタンおよびメタロセン触媒の存在下で、液体を一杯に充填したスラリーループ反応装置中で重合を実行した。メタロセン触媒は活性化し、担体に担持したエチレンビス(4,5,6,7−テトラヒドロ-1-インデニル)ジルコニウム二塩化物である。
比較施例が上記実施例と異なるのはTIBALの含有量である。重合条件は[表1]に示してある。
比較例では重合中に反応装置の壁に汚れ(fouling)が生じたが、実施例では生じなかった。
直列に接続した液体充填した2つのスラリーループ反応装置中で、エチレン、ヘキセン、水素、トリイソブチルアルミニウム、イソブタンおよびメタロセン触媒の存在下で重合を実行した。メタロセン触媒は活性化され担持されたエチレンビス(4,5,6,7−テトラヒドロ-1-インデニル)ジルコニウム二塩化物である。エチレン、ヘキサン、水素、イソブタン、トリイソブチルアルミニウムおよび触媒を[表2]に示す量で反応装置1に導入した。追加のエチレン、追加のヘキセン、追加の水素、追加のイソブタンおよび追加のトリイソブチルアルミニウムを[表2]に示した量で反応装置2に加えた。追加の触媒は反応装置2に導入しなかった。
