A process for producing homopolymers or copolymers of conjugated dienes comprising polymerising the diene monomer with a catalyst system comprising (A) two or more different transition metal compounds (B) a catalyst modifier (eg triphenyl phosphine) and optionally (C) one or more catalyst activators (eg MAO). The cis, trans and 1,2-vinyl microstructure of the produced diene polymer can be controlled.
