Patent
CA 2122821
There is disclosed a highly active catalyst composition for polymerizing alpha- olefins prepared by treating a support with an organomagnesium composition and contacting the thus formed solid support, containing magnesium, with a silane compound of the empirical formula R1x SiR2y wherein Si is silicon atom; x is 1, 2, 3, or 4 and y is 0, 1, 2, or 3, provided that x+y is 4; R1 is R w,-O- wherein O is oxygen and R w is hydrocarbyl of 1 to 10 carbon atoms; and R2 is halogen or hydrocarbyl of 1 to 10 carbon atoms, or hydrogen and a transition metal compound, e.g., a tetravalent titanium compound. This catalyst is particularly useful for the production of linear low density polyethylene polymers. Also disclosed are methods of preparing polymers with the catalyst composition and the resulting polymers.
