    摘要: A catalyst system comprising a) at least one support, b) at least one metallocene and c) at least one compound of the formula (I)  where M1 is an element of group IIa, IIIa, IVa or Va of the Periodic Table of the Elements, x is 0 or 1, y is 0 or 1, z is 0 or 1, A is a cation of group Ia, IIa, IIIa of the Periodic Table of the Elements, a carbenium, oxonium, phosphonium or sulfonium cation or a quaternary ammonium compound, Q1, Q2, Q3 are each a ligand system based on a biphenyl framework bound to M1 via the positions 2 and 12 and having the formula (II)  where R1, R2, R3, R4, R5, R6, R7 and R8 are identical or different and are each a hydrogen atom, a halogen atom, a C1-C40 group, or an OSiR39 group, where R9 are identical or different and are each a hydrogen atom, a halogen atom, a C1-C40 group and two or more radicals R1 to R8 may be joined to one another so as to form a monocyclic or polycyclic ring system which may be substituted.
