    摘要： A method of forming a polymer that simultaneously provides an improved level of impact resistance and processability in which an .alpha.-olefin monomer is subjected to polymerization in the presence of a Ziegler-Natta catalyst system and a blend of electron donors including dicyclopentyldimethoxysilane (DCPMS) and propyltriethoxysilane (PTES). The polymer so formed will have a relationship between a first melt flow rate of a homopolymer formed by polymerizing an .alpha.-olefin monomer in the presence of a Ziegler-Natta catalyst system and a first electron donor (MFR (a)), and a second melt flow rate of a homopolymer formed polymerizing an .alpha.-olefin monomer in the presence of the Ziegler-Natta catalyst system and a second electron donor (MFR (b)), is defined by the equation:1.2.ltoreq.log [MFR(b)/MFR(a)].ltoreq.1.4

    摘要： 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.
