Abstract: A catalyst system comprising a supported catalyst containing a) a solid support, which is a solid methylaluminoxane composition wherein: i) the aluminum content is in the range of 36 to 41 wt % and ii) the mole fraction of methyl groups derived from the trimethylaluminum component relative to the total number of moles of methyl groups is 12 mol % or lower and b) a catalyst thereon which is a metal complex of the formula (1) CyLMZp (1), wherein M is titanium Z is an anionic ligand, p is number of 1 to 2, preferably 2, Cy is a cyclopentadienyl-type ligand and L is an amidinate ligand of the formula (2) wherein the amidine-containing ligand is covalently bonded to the metal M via the imine nitrogen atom, and Sub1 is a substituent comprising a group 14 atom through which Sub1 is bonded to the imine carbon atom and Sub2 is a substituent comprising a heteroatom of group, through which Sub2 is bonded to the imine carbon atom.
