X.I.の測定
2.5gの重合体を撹拌下で、135℃で250mLのo−キシレン中に30分間溶解し、次いで溶液を25℃に冷却し、30分後に不溶性重合体を濾過した。得られた溶液を窒素流れ中で蒸発させた。残留物を乾燥し、秤量して可溶性重合体の比率を求め、差によってX.I.%を求めた。
「Malvern Instr. 2600」装置を使用して単色レーザー光の光学回折の原理に基づいた方法によって測定する。平均粒子サイズは、P50である。
ISO 1133(230℃、2.16Kg)に従って測定する。
この測定は、カルロエルバ(Carlo Erba)社製の「ポロシメーター(Porosimeter)2000シリーズ」を使用して行う。
この試験は、ディスプレイ、恒温槽と共にデュアルインペラシステム、モータ及び調速機を備えた撹拌容器(体積2.5リットル)で実施する。インペラのタイプは、45゜の角度を有するピッチブレードタービンである。インペラタンク直径比は0.6であった。反応器を実施例1に記載されたように製造された触媒スラリーで65体積%で充填した。2m/sの先端速度を40℃の温度で4時間維持する。その後、撹拌を停止し、懸濁液を1mmメッシュでふるいにかける。金属ふるい、容器及び撹拌機は、材料が洗い流さなくなるまでヘキサンで洗浄する。最後に、フィルター、容器及び撹拌機に付着した重合体材料を乾燥させ、収集し、秤量する。
初期量の微小球MgCl2・2.8C2H5OHは、10,000の代わりに3000rpmで作動することを除いては、米国特許第4,399,054号の実施例2に記載されている方法に従って製造した。最終粒子サイズは、P50=28μmであると決定された。
機械式撹拌機、冷却器及び温度計を備えた2.0リットルの丸底フラスコに1.0リットルのTiCl4を窒素雰囲気下で室温で注入した。−5℃で冷却させた後、撹拌しながら、一般的手順で開示したように製造した微小球状体50gを注入した。次いで、温度を−5℃から40℃まで0.4℃/分の速度で上昇させた。40℃の温度に到逹すると、内部供与体として9、9−ビス(メトキシメチル)フルオレン2.8gが導入された。添加終了時に、温度を1.2℃/分の速度で100℃まで上昇させ、この温度で30分間維持させた。その後、撹拌を停止し、固体生成物を沈降させた後、上澄液を温度を100℃に維持しながら吸い上げた。上澄液を除去した後、追加に0.7Lの新しいTiCl4及び11.3gの9、9−ビス(メトキシメチル)フルオレンを添加し、混合物を109℃で加熱し、この温度で30分間維持した。撹拌を再び停止し、固体生成物を沈降させた後、温度を110℃に維持しながら上澄液を吸い上げた。新鮮なTiCl4(0.7L)の3回目の分取量を添加し、混合物を109℃で15分間撹拌下で維持させた後、上澄液を吸い上げた。固体を無水i−ヘキサンで60℃以下の温度勾配で5回(5×1.0リットル)洗浄し、室温で1回(1.0リットル)洗浄した。固体を真空下で乾燥させ、分析した。触媒組成:Mg=11.7重量%;Ti=3.7重量%;I.D.=15.7重量%;P50=27μm。
再循環ガス圧縮機、熱交換器及び自動温度制御装置を備えた流動床反応器を使用して気相でプロピレンを重合させた。予備重合触媒を含む触媒泥は、撹拌容器に供給し、プロパンを連続的に供給する。混合物を20℃で撹拌し、プロピレンピックアップを介して気相反応器に連続的に供給する。連続的且つ一定のプロピレン流れにおいても、他の反応物、すなわちアルミニウムトリエチル(TEAL)、外部供与体としてのメチルシクロヘキシルジメトキシシラン(CMMS)、水素(分子量調節剤として使用される)を、重合温度は75℃、圧力は27bargで設定された流動床反応器に供給する。
予備重合触媒の製造
機械的アンカー撹拌機を備えた2リットルのガラス容器/ステンレス鋼オートクレーブ内に、室温及び窒素雰囲気下で、1.6gのトリ−n−オクチルアルミニウム(TNOA)を含有する1リットルのi−ヘキサン及び前述したように製造された80gの球状触媒を注入した。撹拌は約500rpmに設定し、内部温度は20分間20℃に設定した。反応器の温度を一定に維持しながら、エチレンを約8時間一定の流れで注意深く注入した。触媒1g当たり重合体0.5gの理論転化率に到逹すると重合を中断した。生成された予備重合触媒を室温で真空下で乾燥させ、分析した。これは、固体触媒1g当たりポリエチレン0.52g(34%重合体)含有した。予備重合体組成:Mg=8.4重量%;Ti=2.98重量%;I.D.=10.3重量%;P50=35μm。その後、触媒成分は、それぞれ70℃及び90℃で実施される一般的な手順に従ってプロピレンのダブルラン気相重合に使用した。
予備重合触媒成分のスラリーは、触媒乾燥粒子をWinog 70鉱油に分散させ、乾燥触媒+ヘキサンの重量に対して最終量13重量%のヘキサンを添加することによって製造する。最終スラリー濃度は、スラリー(触媒+オイル+ヘキサン)の総重量に対して乾燥触媒の30重量%である。
触媒1g当たりポリエチレン0.35gの理論転化率に到逹したときに予備重合を中断することを除いては、実施例1に記載されたように触媒成分を製造した。
触媒成分1g当たりポリエチレン1gの理論転化率に到逹したときに予備重合を中断することを除いては、実施例1に記載されたように触媒成分を製造した。
実施例2及び比較例1の予備重合された触媒成分は、前述した一般的な手順に従ってプロピレンの気相重合に使用した。具体的な条件及び結果は、表1に示す。
