CA 2243775

Organometallic complexes having a phosphinimine ligand, a (non- phosphinimine) heteroligand and at least one activatable ligand are catalyst components for olefin polymerization. Preferred polymerization systems are prepared by combining the organometallic complexes with an ionic activator and/or an alumoxane. Preferred catalyst components contain Ti, Zr or Hf and are activated with an ionic activator to provide ethylene polymerization catalysts.
