## Abstract The catalytic properties of bis(phenoxy‐imine) Zr and Hf complexes incorporating perfluorophenyl groups with methylaluminoxane were investigated. The fluorinated complexes produced far higher‐molecular‐weight polyethylenes and ethylene/propylene copolymers with increased activities comp

## Abstract Complexes (R^1^Cp)(R^2^Ind)ZrCl~2~, the catalysts previously reported active for ethylene polymerization showed high activity in ethylene/1‐hexene copolymerization and propylene polymerization in the presence of MAO. The content of 1‐hexene in copolymers ranged from 1.2% to 3.2%. In pro
The copolymerization of styrene and ethylene was attempted in the presence of the catalytic system CpTiCl,methylaluminoxane. Polymerizations were carried out at different polymerization temperatures and Al/Ti mole ratios. The structure of the polymer was investigated with FTIR, DSC, GPC, and "C-NMR
