実施例
[P]=PP+0.5PH
[H]=HH+0.5PH
プロピレン/1-ヘキセンコポリマの13C NMRスペクトルの帰属は、次の表に従って計算される。
C2tot=C2B×成分B(重量%)/100
サンプルを、1,1,2,2-テトラクロロエタン-d2に、120℃で8%wt/vの濃度で溶解した。各スペクトルは、90°パルス、15秒のパルス間の遅延、および1H-13Cカップリングを除去するためのCPDで取得された。9000Hzのスペクトルウィンドウを使用して、512のトランジェントが32Kデータポイントに格納された。
ダイアド分布は、以下の関係に従って算出される。
PP=100I1/Σ
PH=100I2/Σ
HH=100I3/Σ
PE=100I4/Σ
HE=100I6/Σ
EE=100(0.5(I13+I16)+0.25I12)/Σ
ここで、Σ=I1+I2+I3+I4+I6+0.5(I13+I16)+0.25I12
モルパーセントとしての1-ヘキセンとエチレンの総量は、以下の関係を使用してダイアドから算出される。
[P]=PP+0.5PH+0.5PE
[H]=HH+0.5PH+0.5HE
[E]=EE+0.5PE+0.5HE
プロピレン、1-ヘキセン、エチレンの13C NMRスペクトルの帰属
Eモル%=100*[PEP+PEE+EEE] エチレン含有量の重量パーセントは、以下の式を使用して評価された。
100*Eモル%*MWE
E重量%=-------------------
Eモル%*MWE+Pモル%*MWP
ここで、Pモル%は、プロピレン含有量のモルパーセントであり、MWEおよびMWPは、それぞれエチレンおよびプロピレンの分子量である。
