Catalyst mixture

A catalyst complex mixture containing at least one metal complex according to the formula (1)

• CyLMZp (1),
• and at least one metal complex according to the formula (2)
• InLMZp (2),
• wherein
• Cy is a substituted cyclopentadienyl ligand that contains the substituents R1, R2 and 3 additional methyl groups, wherein
• R1 means H, halogen or a C3-C20 substituent, wherein the C3-C20 substituent is an aliphatic or an aryl radical containing from 3 to 23 carbon atoms and wherein the C3-C20 substituent optionally contains heteroatoms selected from the group consisting of halogens, nitrogen, phosphorous, oxygen and sulphur;
• and
• R2 means a C1-C20 substituent, wherein the C1-C20 substituent is an aliphatic or an aryl radical containing from 1 to 20 carbon atoms wherein the C1-C20 substituent optionally contains heteroatoms selected from the group consisting of halogens, nitrogen, phosphorous, oxygen and sulphur;
• In is an indenyl ligand, optionally substituted with one or more substituents R3, wherein the one or more substituents R3 mean independently C1-C20 hydrocarbyl substituents,
• and for each formula (1) and (2) respectively
• M is a group 4 metal
• Z independently is an anionic ligand,
• p is number of 1 to 2, preferably 2, and
• L is an amidinate-type ligand of the formula (3)
• 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 15, through which Sub2 is bonded to the imine carbon atom.
