Abstract
Ziegler-Natta catalysts, processes of forming the same and using the same are described herein. The process generally includes contacting a metal component with a magnesium dihalide support material to form a Ziegler-Natta catalyst precursor; contacting the support material with a dopant including a non-Group IV metal halide to form a doped catalyst precursor; and activating the doped catalyst precursor by contact with an organoaluminum compound to form a Ziegler-Natta catalyst.
