Oxo-nitrogenated complex of lanthanides, catalytic system comprising said oxo-nitrogenated complex and process for the (co)polymerization of conjugated dienes.

摘要

An oxo-nitrogenated complex of lanthanides having general formula (I) or (II). Said oxo-nitrogenated complex of lanthanides having general formula (I) or (II) can be advantageously used in a catalytic system for the (co)polymerization of conjugated dienes.
