ABSTRACT OF THE DISCLOSURE SUPPORTED POLYOLEFIN CATALYST COMPONENTS AND METHODS OF MAKING AND USING THE SAME A method of producing a polymerization catalyst component suitable for use in the polymerization of alpha-olefins, which method comprises forming an active component by co-comminuting an inorganic Lewis acid, a first organic electron donor, a support base selected from the group consisting of the Group IIA & IIIA salts and the salts of the multivalent metals of the first transition series with the exception of copper, and a polymerization active tri-, tetra-, or penta- valent transition metal compound of a Group IVB-VIB metal, and heating the active component in an inert hydrocarbon solvent to produce the polymerization catalyst component. The active component can be heated in the inert hydrocarbon solvent in the presence of an additional polymerization active tri-, tetra-, or penta- valent transition metal compound of a group IVB-VIB metal. In addition, a second organic elec- tron donor may be incorporated in the active component.
