Abstract:
1. A solid titanium catalyst component for the polymerization of olefins, comprising: an inorganic titanium compound; a magnesium alcohol adduct made by contacting an inorganic magnesium compound, an alcohol, and an organic medium, wherein the alcohol and the inorganic magnesium compound are contacted at a molar ratio of the alcohol to the inorganic magnesium compound from about 0.1:1 to about 1:0.1, and wherein the organic medium and the inorganic magnesium compound are contacted at a molar ratio of the organic medium to the inorganic magnesium compound from about 1:1 to about 50:1; and a porous support having at least one of a specific surface area of about 100 m the solid titanium catalyst component having a diameter from about 20 microns to about 150 microns (on a 50% by volume basis).
