Metal complexes containing bridged, non-aromatic, anionic, dienyl groups
and addition polymerization catalysts therefrom
摘要:
Catalytic derivatives of novel Group 4 metal complexes wherein the metal is in the +2, +3, or +4 formal oxidation state containing two ligand groups bound by .pi.-electrons, at least one of which is a cyclic or noncyclic, non-aromatic, anionic, dienyl ligand group and having a bridged ligand structure, and the use thereof as catalysts for polymerizing addition polymerizable monomers are disclosed.
