Abstract

A process is described for the homo- and co-polymerization of conjugagted dienes characterized in that it is carried out in the presence of a catalytic system comprising a complex having general formula (II): Fe(L)n(X)s wherein n is an integer ranging from 1 to 3; X is independently a group of an anionic nature bound to Fe(II) as an anion in an ionic couple or with a covalent bond of the σ type; 's' expresses the number of x groups sufficient for neutralizing the formal oxidation charge of Fe(II), and is equal to 2 if all the X groups are monovalent; L is a ligand having general formula (I)
