上記で調製したエチレン-プロピレン共重合触媒を含む攪拌機付オートクレーブに、液化プロピレン15モル(1.2リットル)および水素ガス0.20MPa(分圧)を装入し、20℃で5分間予備重合を行なった後に昇温し、70℃で45分間、1段目のプロピレン単独重合反応(単独段重合)を行なった後、常圧に戻し、次いでオートクレーブ内(リアクター内)を窒素置換してからオートクレーブの計量を行ない、オートクレーブの風袋質量を差し引いて、上述した方法と同様の方法により単独段(1段目)の重合活性(g-PP/g-触媒)を算出し、重合性能及びポリマー物性(細孔容積)の評価用として、生成した一部のポリマーを分取した。
次に、エチレン/プロピレンを、それぞれモル比が1.0/1.0となるように上記オートクレーブ内(リアクター内)に投入した後、70℃まで昇温し、エチレン/プロピレン/水素を、それぞれ1分あたりのガス供給量(リットル/分)が2/2/0.086の割合となるように導入しつつ、1.2MPa、70℃、60分間の条件で反応させることにより、エチレン-プロピレン共重合体を得た。
生成したエチレン-プロピレン共重合体粒子について、以下の方法により、プロピレン系ブロック共重合活性(ICP(インパクトコポリマー)重合活性)、得られたプロピレン系ブロック共重合体中のEPR(エチレン-プロピレンゴム成分)含有量(wt%)、共重合体粒子の流れ性および重合体粒子内部におけるEPR(エチレン-プロピレンゴム成分)分散状態を、各々、以下の方法により測定した。結果を表3に示す。
固体触媒成分1g当たりのプロピレン系ブロック共重合活性を、下記式により求めた。
プロピレン系ブロック共重合活性(g-ICP/g-触媒)
=(I(g)-F(g)+J(g))/[{オレフィン類重合用触媒中の固体触媒成分の質量(g)×((G(g)-F(g)-J(g))}/(G(g)-F(g)))]
ここで、Iは共重合反応終了後のオートクレーブ質量(g)、Fはオートクレーブ質量(g)、Gはプロピレン単独重合終了後、未反応モノマーを除去した後のオートクレーブ質量(g)、Jは単独重合後に抜き出したポリマー量(g)である。

以下の方法により、生成した重合体の流れ性を測定した。
図10に示すように、出口位置にダンパーDを介設した漏斗F(上部口径;91mm、ダンパー位置口径;8mm、傾斜角;20°、ダンパー位置までの高さ;114mm)を上部にセットし、上記ダンパーDの下部に38mmの間隔を置いて容器状の受器C(内径;40mm、高さ;81mm)を設置した装置を用い、先ず上部の漏斗Fに重合体50gを投入後、室温(20℃)下において、ダンパーDを開口して重合体を受器Cに落下させ、全ての重合体が落下する時間を計測した。
上記操作により計測した、重合体50gの落下時間T1(秒間)から、下記の式により1秒あたりの重合体落下量(g/sec)を算出し、重合体流動性の評価指標とした。
重合体流動性(1秒あたりの重合体落下量(g/sec))=50÷T1
以下の方法により、生成した共重合体粒子内部を観察し、細孔の分散度合いを求めた。
無作為に選択した共重合体粒子200個を、フィルジェン社製の真空電子染色装置(VSC1R1H)により、濃度5で、5分間、四酸化ルテニウムを用いてEPR成分に染色を行った。
ビューラー社製 エポキューアー2を用いて樹脂剤80重量%、硬化剤20重量%に調合し、1インチの透明カップの中で上記染色した共重合体粒子と調合したエポキューアー2を混合し硬化するまで室温で放置した。
上記混合、硬化して得られた硬化物を収容した1インチのカップを、研磨が出来るようにビューラー社製 アイソメトカッターで切断し、得られた切断物を、日本電子(株)製精密平面研磨機 ハンディラップ(HLA-2)を用い、#600(JIS規格)から#5,000(JIS規格)の研磨紙で丁寧に水による湿式研磨を続けた。
最後にビューラー社製 オートメット250に全体荷重バレル3個掛けし、研磨バフにマスターテックスを装着し、伸展液に水道水、回転数をヘッドに60rpm/ベース150rpmで同方向で90秒最終仕上げを行い、水分をエアーで吹き飛ばした。
得られた共重体粒子断面を(株)ニコン製 ECLIPSE LV100NDAで観察した。
得られた顕微鏡写真において、黒色で示される箇所として四酸化ルテニウムによって染色されたEPR充填部(エチレンープロピレンゴムが充填された細孔部)、白色で示される箇所としてPP部位(プロピレン単独重合部)を各々確認することができ、本例においては、共重合体粒子断面に観察される細孔のほぼ全てにEPRが充填されていることを確認することができた。
上述したオレフィン類重合用固体触媒成分の断面細孔面積率および平均細孔面積率の比MXi/MXsの測定方法(画像解析方法)において、共重合体粒子断面像を(図4に例示するような)2諧調化した粒子断面像に変更し、組織部(平面部)に代えてPP部位を、細孔部(凹部)に代えてEPR充填部を解析対象とした以外は、上述した方法と同様の方法により、共重合体粒子断面において、粒子中心から半径方向50%以上の領域の断面細孔面積率(M'Xs)および半径方向50%未満の領域の断面細孔面積率(M'Xi)を各々算出したところ、半径方向50%以上の領域の断面細孔面積率(M'Xs)に対する半径方向50%未満の領域の断面細孔面積率(M'Xi)の比M'Xi/M'Xs比は1.02であった。結果を表3に示す。

結果を表1~表3に示す。
本発明の比較例に相当する固体触媒成分を用い、実施例1と同様にして、重合触媒の形成および重合を行い、実施例1と同様にそれぞれ評価した。
このとき得られた共重合体粒子の(2諧調化処理前における)共重合体粒子の断面観察写真を図11に示す。
図11において、黒色で示される四酸化ルテニウムによって染色されたEPR充填部(エチレンープロピレンゴムが充填された細孔部)が、白色で示されるPP部位(プロピレン単独重合部)に対し、粒子断面の周縁部から中央部に食い込むように比較的全体的に分布していることを確認することができた。
これは、上記固体触媒成分が、特定の断面細孔面積率およびMXi/MXsを有することにより、強度が高く重合中に容易に破壊されない構造を有し、微粉粒子の含有割合が低い触媒粒子を形成し得たためと考えられる。
また、上記固体触媒成分を用いることにより、各固体触媒成分のMXi/MXsに対応するM’Xi/M’Xsを有する重合体を製造することができ(表2および表3参照)、得られる共重合体粒子の流れ性が低く表面のベタツキを抑制し得ることが分かる(表3参照)。
これは、固体触媒成分として特定の断面細孔面積率およびMXi/MXsを有する固体触媒成分を用いることにより、特定の細孔分布を有する共重合体粒子を生成することができ、PP(プロピレン単独重合体)により形成される共重合体微細孔骨格構造の専ら周縁部の細孔内にEPR(エチレンープロピレンゴム)が存在することにより、ゴム成分の表面付着や染み出しを抑制し、ベタツキを抑制し得たためと考えられる。
このため、実施例1~実施例10においては、オレフィン類の重合に供したときに、微粉状物の含有割合が低減されていたり、流れ性が低く重合体粒子表面のベタツキが抑制された重合体粒子を高活性下に製造し得ることが分かる。
