Supported phosphinimine-cyclopentadienyl catalysts

摘要

A catalyst component which is especially useful in so-called "slurry" or "gas phase" olefin polymerizations and which comprises an organmetallic complex of a froup 4 metal (having a cyclopentadienyl ligand and a phosohinimine ligand) and a particulate support. The catalyst component forms an excellent catalyst system when combined with an activator such as an aluminoxane or a so-called "substantially non-coordinating anion". In a preferred embodiment the organometallic complex and the activator are both deposited on the particulate support.
