Patent ID: 7473664

Claim:
A process of forming a catalyst system comprising: contacting an alkyl magnesium compound with an alcohol to form a magnesium dialkoxide compound; contacting the magnesium dialkoxide compound with a first compound and a second compound to form reaction product “A”, wherein the second compound comprises a metal halide and the first compound is represented by the formula A(O x R 4 ) y , wherein A is selected from titanium, silicon, aluminum, carbon, tin and germanium, R 4 is selected from C 1 to C 10 alkyls, x is 0 or 1 and y is the valence of A; contacting reaction product “A” with a second agent to form reaction product “B”, wherein the second agent comprises a transition metal and a halogen; contacting reaction product “B” with a third agent to form reaction product “C”, wherein the third agent comprises a first metal halide; optionally contacting reaction product “C” with a fourth agent to form reaction product “D”, wherein the fourth agent comprises a second metal halide; and contacting reaction product “D” with fifth agent to form a Ziegler-Natta catalyst component, wherein the fifth agent comprises an organoaluminum compound.
