Abstract
A catalyst component which is especially useful in so-called 'slurry' or 'gas phase' olefin polymerizations and which comprises an organometallic complex of a group 4 metal (having a cyclopentadienyl-type ligand and a phosphinimine 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.
