Abstract

The present invention is directed to a coordinating catalyst system comprising at least one pre-catalyst selected from late transition metal bidentate or tridentate ligand containing compounds, at least one support-agglomerate having chromium immobilized thereto (e.g., spray dried silica/clay agglomerate), and optionally at least one organometallic compound in controlled amounts, and methods for preparing the same. The resulting catalyst system exhibits enhanced activity for polymerizing olefins and yields polymer products having very good morphology.
