    摘要: Disclosed is a process for making a Ziegler-Natta catalyst having controlled particle size and distribution. It comprises altering the precipitation of a catalyst component from a catalyst synthesis solution including a soluble magnesium containing catalyst precursor by controlling the concentration of either the soluble magnesium containing catalyst precursor, wherein the average particle size of the catalyst component is increased, and the particle size distribution increased, with a decreased concentration of the soluble magnesium containing catalyst precursor; or of the precipitating agent, wherein the average particle size of the catalyst component is increased, and the particle size distribution increased with an increased concentration of the precipitating agent. Use of the invention enables improved catalyst consistency regardless of production scale and customizing of catalyst morphology to desired polymer morphology. The novel catalyst components may be used to prepare polymers, and end-use articles therefrom, having desirable properties.

    摘要: The invention provides a process for forming a catalyst for use in the polymerization of olefins. This process comprises reacting a chlorinating agent with a magnesium alkoxide compound to form a magnesium-titanium-alkoxide adduct, followed by reacting the magnesium-titanium-alkoxide adduct with an alkylchloride compound, e.g., benzoyl chloride, to form a magnesium chloride support. The support is then reacted with titanium tetrachloride to form a highly active catalyst useful for the production of polyolefins.
