Abstract:
Catalyst component composition adapted for ethylene polymerization prepared by the process comprising:(a) impregnating particulate inorganic oxide support with at least one organomagnesium compound to form a first reaction product;(b) halogenating the first reaction product to convert the organomagnesium derived component thereof to magnesium halide, thereby forming a second reaction product;(c) treating the second reaction product with:(i) at least one Group 4 or 5 transition metal compound,(ii) at least one alkyl di- or tri-substituted pyridine electron donor wherein the substituents are at least located at the 2- and 6-positions, and optionally at the 3-, 4-, or 5- positions, of the aromatic pyridine ring, and optionally,(iii) at least one Group 2 or 13 organometal compound.
