Compounds and metal complexes comprising a polycyclic, fused ring ligand or inertly substituted derivative thereof having up to 60 atoms other than hydrogen, said ligand comprising at least: (1) a cyclopentadienyl ring, (2) a 6,7, or 8 membered ring other than a 6-carbon aromatic ring, and (3) an aromatic ring, with the proviso that said 6, 7, or 8 membered ring (2), is fused to both the cyclopentadienyl ring (1), and the aromatic ring (3), polymerization catalysts, a process to prepare the novel compounds and complexes, and olefin polymerization processes using the same are disclosed.
La présente invention concerne des composés et des complexes métalliques comprenant un ligand polycylicique à cycles accolés ou un de ses dérivés substitués de façon inerte, ayant jusqu'à 60 atomes autres que l'hydrogènes, ledit ligand comprenant au moins: (1) un cycle cyclopentadiényle; (2) un cycle à 6,7, ou 8 éléments différent du cycle aromatique à 6 atomes de carbone; et (3) un cycle aromatique. L'invention se caractérise en ce que le cycle à 6,7, ou 8 éléments (2) est accolé à la fois au cycle cyclopentadiényle (1) et au cycle aromatique (3). Cette invention concerne également des catalyseurs de polymérisation, un procédé permettant de préparer les composés et complexes de l'invention, et des procédés de polymérisation oléfinique faisant intervenir l'utilisation desdits composés et complexes.
