Nitrogen substituted phosphinimine ligand |
摘要 |
An organometallic complex of a group 4 metal having a cyclopentadienyl ligand and a heterosubstituted phosphinimine ligand is a catalyst component for olefin polymerization. The heterosubstituted phosphinimine ligand may be conveniently and inexpensively synthesized using readily available precursors which are comparatively non-pyrophoric. The resulting catalysts are highly active for ethylene copolymerization, particularly when activated with an alumoxane or ionic activator.
