Abstract: A highly active catalyst suitable for the polymerization of olefins and its use are disclosed, said catalyst being prepared by (1) co-comminuting an aluminum halide; at least one electron donor; a Group IVB-VIB transition metal compound; and a support base selected from the group consisting of the Group IIA and IIIA salts and the salts of the multivalent metals of the first transition series with the exception of copper to produce a coground solid; (2) extracting said coground solid with an organic liquid; and (3) separating the solid from the liquid under such conditions that at least 5 weight percent of the aluminum in the coground solid is removed.

Abstract: A supported high efficiency catalyst component for polyolefin production and methods of making and using the same are disclosed. A catalyst support made from a solid, particulate support material, a second solid material preferably substantially isostructural therewith and an organic electron donor compound is combined with a polymerization-active transition metal compound and optionally a second organic electron donor compound to form the catalyst component. Additionally, a dehydrating agent may be reacted with water in the solid, particulate support material in the production of the catalyst support. The methods of producing such a catalyst support and catalyst component are preferably performed by severe milling in the absence of any solvent. Such a catalyst produces polymer of such high quality and quantity that polymer extraction and polymer deashing are not necessary.
