Abstract of the Disclosure: Catalyst systems for the polymerization of C.sub.2 -C.sub.10 -alk-1-enes contain, as active components,

Soluble catalyst systems for the preparation of polyalk-1-enes having

A process for polymerizing C.sub.2 -C.sub.10 -alk-1-enes in the presence of a metallocene complex of the formula I ##STR1## where the substituent groups have the meanings described in the specification.

Polymerization process using metallocene complexes in the catalyst system

A supported catalyst system that is obtained by

Supported metallocene complexes having heterofunctional groups in the

Metallocene complexes of the general formula I ##STR1## where the substituents Y, M, x, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.6, R.sup.7, R.sup.8, and R.sup.9 are as described in the disclosure, and ligand systems of the general formula II ##STR2## as intermediates.

Metallocene complexes having heterofunctional groups in the

Catalyst systems for the polymerization of C.sub.2 -C.sub.10 -alk-1-enes contain, as active components,

Catalyst systems for the polymerization of C.sub.2 -C.sub.10 -alk-1-enes

Polymers of C.sub.2 -C.sub.10 -alk-1-enes are prepared at from 0.5 to 3000 bar and from -50.degree. to 300.degree. C. using a catalyst system by a process in which the catalyst system used is one which contains, as active components: a) a metallocene complex of the general formula I ##STR1## where M is titanium, zirconium, hafnium, vanadium, niobium or tantalum, X is fluorine, chlorine, bromine, iodine, hydrogen, C.sub.1 -C.sub.10 -alkyl, C.sub.6 -C.sub.15 -aryl or --OR.sup.7,

Preparation of polymers of C.sub.2 -C.sub.10 -alk-1-enes using racemic

The present invention relates to soluble catalyst systems for the polymerization of C.sub.2 - to C.sub.10 -alk-l-enes, containing, as active constituents,

Soluble catalyst systems for the polymerization of C.sub.2 - to C.sub.10
