“…7,17 Their superior properties include high glass transition temperatures, excellent optical transparency, low birefringence and good solubility in common organic solvents and serve as reasons for the increased interest. 7,17 Many transition metal complexes including titanium, 18,19 zirconium, 20,21 31 We report herein the preparation of new nickel (II) complexes bearing a fluorinated β-diketiminate backbone ligands. The catalytic polymerization of norbornene was investigated when activated by MAO.…”
