ABSTRACT:
Described is a magnesium-transition metal containing catalyst component, comprising a solid reaction product obtained by treating a solid support material in an inert solvent in any order with (A) a halogenated silane compound, (B) an alkoxy-containing magnesium compound, (C) and acyl halide, (D) at least one transition metal compound of a Group IVb-VIb or VIII metal, and optionally (E) treating the magnesium-transition metal containing product with an organometallic compound of a Group IIa, IIb, or IIIa metal. The magnesium-transition metal containing catalyst component, when employed with known Ziegler cocatalyst, provides a catalyst system which have very high catalytic activities for production of polyolefin of high bulk density. The polymerization kinetics of the catalyst system is controllable as a function of the reagent molar ratios selected for production of the magnesium-transition metal containing catalyst component.
