摘要：A method of producing a polymerization catalyst component suitable for use inthe polymerization of alpha-olefins, which method comprises forming an active

component by co-comminuting an inorganic Lewis acid, a first organic electron donor, asupport base selected from the group consisting of the Group IIA & IIIA salts and thesalts of the multivalent metals of the first transition series with the exception of copper,and a polymerization active tri-, tetra-, or pentavalent transition metal compound of aGroup IVB-VIB metal, and heating the active component in an inert hydrocarbon solventto produce the polymerization catalyst component. The active component can be heatedin the inert hydrocarbon solvent in the presence of an additional polymerization activetri-, tetra-, or penta- valent transition metal compound of a group IVB-VIB metal. Inaddition, a second organic electron donor may be incorporated in the active component.
