Abstract
Nonmetallocenes, process for preparing them and their use for the polymerization of olefins. The present invention describes a novel group of specific transition metal compounds, referred to as nornmetallocene compounds, and catalyst systems prepared therefrom. These catalyst systems which have become obtainable for the first time are suitable for the polymerization of olefins.
