Abstract: The present invention relates to a catalyst 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 and
R2 means a C1-C20 substituent,
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 independently for each formula (1) and (2)
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 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.-
