Abstract:
A process for producing a fulvene metal complex containing catalyst system comprising the step of thermally treating in a suitable reaction medium, a mixture of an aluminoxane- and boron-free Lewis acid suitable for activation and a metal complex of formula (II) ##STR3##whereinM is a metal cation from the group IIIb, IVb, Vb, VIb or of the lanthanides or of the actinides of the Periodic Table of the Elements [N. N. Greenwood, A. Earnshaw, Chemie der Elements, VCH 1990],A signifies an optionally uni- or multi-bridged anionic ligand, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, and R.sup.7 are identical or different and stand for hydrogen, halogen, a cyano group, a C.sub.1 to C.sub.20 alkyl group, a C.sub.1 to C.sub.10 fluoroalkyl group, a C.sub.6 to C.sub.10 fluoroaryl group, a C.sub.1 to C.sub.10 alkoxy group, a C.sub.6 to C.sub.20 ayryl group, a C.sub.6 to C.sub.10 aryloxy group, a C.sub.2 to C.sub.10 alkenyl group, a C.sub.7 to C.sub.40 arylalkyl group, a C.sub.7 to C.sub.40 alkylaryl group, a C.sub.8 to C.sub.40 arylalkenyl group, a C.sub.2 to C.sub.10 alkinyl group, an optionally substituted silyl group or form respectively together with the atoms linking them one or more ring systems, which can contain one or more hetero atoms,X stands for hydrogen, halogen, a C.sub.1 to C.sub.30 alkyl group, a C.sub.6 to C.sub.10 aryl group, a C.sub.2 to C.sub.10 alkenyl group, a C.sub.7 to C.sub.40 arylalkyl group, a C.sub.7 to C.sub.40 alkylaryl group, a C.sub.8 to C.sub.40 arylalkenyl group, a C.sub.2 to C.sub.10 alkinyl group, and an optionally silyl group.
