Monocyclopentadienyl metal catalyst composition for the polymerization of olefins

摘要

A catalyst composition for the polymerization of olefins is provided. The catalyst composition comprises a monocycloalkadienyl/metal/ligand catalyst precursor, wherein at least one ligand is capable of multihapto attachment to the metal atom through a carbon or hydrogen atom, and a cocatalyst capable of irreversibly abstracting a ligand from the catalyst precursor.
