The invention relates to a catalyst system for the polymerization of olefins comprising a metal complex of formula CyLMD and an activating cocatalyst, wherein M is titanium, Cy is a cyclopentadienyl-type ligand, D is a diene, L is an amidinate-containing ligand of formula (1), wherein the amidinate-containing ligand is covalently bonded to the titanium via the imine nitrogen atom, Subis a substituent, which comprises a group 14 atom through which Subis bonded to the imine carbon atom, Subis a substituent, which comprises a nitrogen atom, through which Subis bonded to the imine carbon atom, and Cy is a mono- or polysubstituted cyclopentadienyl-type ligand, wherein the one or more substituents of Cy are selected from the group consisting of halogen, hydrocarbyl, silyl and germyl residues, optionally substituted with one or more halogen, amido, phosphido, alkoxy, or aryloxy residues. The invention further relates to a process for the preparation of a polymer comprising at least one aliphatic or aromatic hydrocarbyl Colefin wherein the at least one aliphatic or aromatic olefin is contacted with the catalyst system of the present invention.
