A process for the preparation of indanones of the formula II from indanones of the formula I or of indanones of the formula IIa from indanones of the formula Iacomprises reacting an indanone of the formula I or Ia with a coupling component.

Preparation of preparing substituted indanones

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.
