Titanium complexes comprising a 3-aryl-substituted cyclopentadienyl ring or substituted derivative thereof and at least one additional aryl substituent on the cyclopentadienyl ring, polymerization catalysts, and olefin polymerization processes using the same are disclosed.

3-aryl-substituted cyclopentadienyl metal complexes and polymerization process

Metal complexes comprising a polydentate chelating group, catalysts and polymerization processes using the same for the polymerization of olefins, especially propylene, are disclosed.

Transition metal complexes and olefin polymerization process

Metal complexes comprising a polycyclic, fused ring ligand or inertly substituted derivative thereof comprising at least: (1) a cyclopentadienyl ring, (2) a 7 membered polyatomic ring, and (3) one or more aromatic ring systems, with the proviso that said 7 membered ring (2), is fused to both the cyclopentadienyl ring (1), and said one or more aromatic ring systems (3), and substituted in at least one ring position with a substituent group resulting in sp hybridization on the ring atom bonded thereto; polymerization catalysts; and olefin polymerization processes using the same are disclosed.
