Patent ID: 8003741

Claim:
A process of forming a catalyst comprising: contacting an alkyl magnesium compound with alcohol to form a magnesium dialkoxide compound; contacting the magnesium dialkoxide compound with a plurality of first agents to thereby form a solid reaction product “A”, wherein the plurality of first agents comprises a first compound, a second compound, and a third compound; wherein the first and second compounds are independently represented by the formula: A(O x R′X 1 ) y (O x R″X 2 ) z wherein A is independently selected from titanium, silicon, aluminum, carbon, tin and germanium; X 1 and X 2 are optional and when one and/or the other are present, they are the same or different heteroatoms; R′ and R″ are independently selected from C 1 -C 10 alkyls which may be linear, branched, aromatic or cyclic; x is 0 or 1; and y+z is the valence of A; wherein the first and second compounds are contacted with the magnesium dialkoxide in the substantial absence of metal halide; and wherein the third compound is contacted last and consists essentially of unblended TiCl 4 ; contacting reaction product “A” with a second agent to form reaction product “B”, wherein the second agent comprises a metal halide; and contacting reaction product “B” with a third agent to form a catalyst, wherein the third agent comprises an organoaluminum compound.
