Ethylene and ethylene/propylene polymerization behavior of bis(phenoxy-imine) Zr and Hf complexes with perfluorophenyl substituents

摘要

The catalytic properties of bis(phenoxyimine) 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 compared with the non-fluorinated congeners. Moreover, the fluorinated complexes displayed a higher incorporation ability for propylene. [References: 32]
