TRANSITION METAL OLEFIN POLYMERIZATION CATALYST HAVING CYCLOPROPENYL DERIVED LIGANDS |
摘要 |
This invention is directed to cationic polymerization of olefins using catalysts comprising a Group 6 or 10 neutral transition metal cation composition having a cyclopropenyl ring, a pi-bonded cyclopentadienyl ligand or cyclopentadienyl group-containing ligand and an amido or imido ligand. The precursor of the neutral transition metal composition is activated to a catalytic state by exposure to an activator composition that may be any of the heretofore known activator compositions such as an alumoxane or a compatible non-coordinating anion (NCA). |
