ABSTRACT:
The invention discloses a method for making a hydrogenated metallocene catalyst component comprising the steps of: 1. Providing a compound comprising at least one aromatic group; 2. Hydrogenating the at least one aromatic group in the presence of hydrogen and a hydrogenation catalyst to form a hydrogenated compound; and 3. Forming a metallocene catalyst component from the hydrogenated compound from step 2.
