ABSTRACT A supported high efficiently 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 poly- merisation-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.
