測定装置:GC-2010(島津製作所社製)
カラム:DB-1 60m 膜厚 0.25μm 内径0.25mm
昇温パターン:50℃にて10分保持→5℃/分で200℃まで昇温→20分保持

反応液を、エタノールとメタノールの混合溶媒に投入し、析出した組成物を濾過にて捕集し、80℃にて減圧乾燥し、重量を測定して求めた。
固体状ポリメチルアルミノキサンおよび変性固体状ポリメチルアルミノキサンのメジアン径および粒度分布は、下記の測定装置を利用し、乾燥させた下記の測定溶媒中でレーザー回折・散乱法により求めた。
測定装置:SALD-2200J
測定溶媒:n-ヘキサン
粒度分布の指標はSpan値を用いた。
Span値=(D90-D10)/D50
(ここでD10、D50、D90は、上記の方法により測定した粒度分布の累積分布関数の値がそれぞれ10%、50%、90%となるときの粒径の値である。)
固体状ポリメチルアルミノキサンおよび変性固体状ポリメチルアルミノキサンのアルミニウム含有量は次のようにして測定した。まず窒素雰囲気下で純水中に固体状ポリメチルアルミノキサンまたは変性固体状ポリメチルアルミノキサンを加え、これを空気中に取り出して加熱し、水を全て蒸発させた。析出した固体に炭酸ナトリウムを加えた後、加熱して溶融させ、Varian社製のVista-PROを使用したICP-AES法によりアルミニウム含有量を求めた。
m/(m+n)の値は次のように算出した。変性固体状ポリメチルアルミノキサンの製造において、原料である固体状ポリメチルアルミノキサンにハロゲン化アルコールまたはハロゲン化フェノール類を加えると、反応したハロゲン化アルコールまたはハロゲン化フェノール類と等モル量のメタンが生成する。このことを考慮し、固体状ポリメチルアルミノキサンのアルミニウム含有量をXwt%、変性固体状ポリメチルアルミノキサンのアルミニウム含有量をYwt%、ハロゲン化アルコールまたはハロゲン化フェノール類の分子量をMとすると、YはX、M、およびm/(m+n)を用いて次のように表すことが出来る。
したがってm/(m+n)の値は次式で求められる。
触媒活性の指標としては、反応により得られた1-ヘキセンの重量を使用した錯体の物質量で除した値(t/mol錯体)、および反応により得られた1-ヘキセンの重量を使用した共触媒(シリカ/ポリメチルアルミノキサン、固体状ポリメチルアルミノキサン、または変性固体状ポリメチルアルミノキサン)の重量で除した値(g/g共触媒)を用いた。
