OXO-NITROGENATED COMPLEX OF COBALT, CATALYTIC SYSTEM COMPRISING SAID OXO-NITROGENATED COMPLEX AND PROCESS FOR THE (CO) POLYMERIZATION OF CONJUGATED DIENES

摘要

The present invention relates to an oxo-nitrogenated complex of cobalt having the general formula (I) wherein the residues R1, R2, R3, X1 and X2 are as defined in the claims. Said oxo-nitrogenated complex of cobalt having general formula (I) can be advantageously used in a catalytic system for the (co) polymerization of conjugated dienes.
