COMPLEJOS DE TITANIO (II) O CIRCONIO (II) Y CATALIZADORES DE POLIMERIZACION POR ADICION OBTENIDOS A PARTIR DE LOS MISMOS.

摘要

Novel catalytic derivatives of titanium or zirconium complexes containing one and only one cyclic delocalized, anionic, +529 -bonded group wherein the metal is in the +2 formal oxidation state and having a bridged ligand structure and an activating cocatalyst are useful as catalysts for polymerizing olefins, diolefins and/or acetylenically unsaturated monomers.
