Abstract
Processes of forming catalyst systems, catalyst systems and polymers formed therefrom are described herein. The processes generally include providing a first compound including a magnesium dialkoxide, contacting the first compound with a second compound to form a solution of reaction product “A”, wherein the second compound is generally represented by the formula:Ti(OR1)4;wherein R1 is selected from C1 to C10 linear to branched alkyls, contacting the solution of reaction product “A” with a first metal halide to form a solid reaction product “B”, contacting solid reaction product “B” with a second metal halide, to form reaction product “C” and contacting reaction product “C” with reducing agent to form a catalyst component.
