Metal complexes containing partially delocalized II-bound groups and addition polymerization catalysts therefrom |
摘要 |
Novel Group 4 metal complexes wherein the metal is in the +2 or +4 formal oxidation state containing a cyclic or noncyclic, non-aromatic, anionic, dienyl ligand group bound to M and having a bridged ligand structure, catalytic derivatives of such complexes including novel zwitterionic complexes; and the use thereof as catalysts for polymerizing addition polymerizable monomers are disclosed.
