ESR Studies on Ziegler-Natta Catalyst Systems
The Journal of the Society of Chemical Industry, Japan, 1970 各種 TiCl3 の ESR 測定を行なった。TiCl3 (A型あるいはH型) では, TiCl3 (AA型) に見られるような g 値 1.94 の鋭い収は認められなかった。しかし, TiCl3 (A型あるいはH型) をボールミル磨砕した試料からは, g 値 1.94 の吸収が認められた。 さらに Ticl3 (A型) に, オレフィンあるいはアルキルアルミニウムを添加するとこの吸収が出現する。TiCl3 (AA型) に対する各種アルキルアルミニウムの影響を ESR で調べた。g 値 1.97 の吸収強度は, 重合活性序列 AlEt3>ALEt2Cl>AlEtCl2≒0 と非常に良い相関を示していることが判った。TiCl3 (AA型)-AlEt3, TiCl3 (AA型)-AlEt2Cl ...
