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 sp2 hybridization on the ring atom bonded thereto; polymerization catalysts; and olefin polymerization processes using the same are disclosed.
本发明涉及一种
金属配合物,包括多环融合环
配体或其惰性取代衍
生物,至少包括:(1)一个
环戊二烯基环,(2)一个7元多原子环,和(3)一个或多个芳香环系统,但前提是所述的7元环(2)与
环戊二烯基环(1)和所述的一个或多个芳香环系统(3)融合,并在至少一个环位置上被取代基取代,从而导致所连接的环原子的sp2杂化;本发明还涉及聚合催化剂以及使用该催化剂的烯烃聚合过程。
