Abstract
A method for making magnesium-halide supports of a specified particle shape, average diameter and particle diameter distribution comprises providing a non-aqueous solution of a magnesium-halide containing silica particles dispersed therein, and crystallizing the magnesium-halide about the silica particles to provide the magnesium-halide support, wherein the magnesium-halide support has an approximately spherical shape, an average particle diameter from about 2 to about 120 microns, and a particle diameter distribution from about 1 to about 200, are provided. The invention further provides methods for making catalysts and using same in polymerization reactions. Catalyst supports and catalysts are also provided.
