A process for the polymerization of olefins, in particular a process for the copolymerization of propylene with further olefins, is carried out in the presence of highly active catalyst systems comprising specifically selected metallocenes, in particular ones which bear different substituents in position 2 and position 4 on an indenyl ligand. Novel polypropylene copolymers can be obtained by this process.

The present invention relates to a process for preparing a metallocene, which comprises reacting a ligand starting compound with an adduct of the formula (I),MXD&#x2003;&#x2003;(I)

Method for producing metallocenes

A process for purifying metallocenes in which a sparingly soluble metallocene halide is converted into a readily soluble and readily crystallizable metallocene by replacement of at least one halide ligand by an alternative negatively charged ligand and the metallocene obtained in this way is subsequently purified by crystallization.

Method for producing monoaryloxy-ansa-metallocenes

The invention relates to a catalyst system obtained by mixing at least one metallocene, at least one co-catalyst and at least one support which is rendered inert. The invention further relates to a method for producing a free flowing supported catalyst system wherein a) a metallocene/co-catalyst mixture is produced in a solvent or suspension agent, b) the metallocene/co-catalyst mixture is applied to a porous preferably inorganic dehydrated support, c) the solvent is removed from the resulting mixture, d) the supported catalyst system is isolated. The present invention also relates to homopolymers and/or copolymers having the preferred formula R &mdash;CH&boxH;CH&mdash;R for the monomer, wherein R and R are the same or different and mean a hydrogen atom or a group containing carbon with 1 to 10 C atoms, and R and R can form one or several rings with the binding atoms, which can be obtained with a catalyst system. Finally, the invention relates to the use of the inventive polymers from producing tear-resistant, hard and stiff shaped bodies such as fibers, filaments, injection-molded parts, films, plates or large hollow bodies such as tubes.
