ABSTRACT:
A non-supported solid catalyst comprising (a) an ionic compound comprising a.1) a cation and a.2) an anion having up to 100 nonhydrogen atoms and said anion containing at least one substituent comprising an active hydrogen moiety, (b) a transition metal compound, and (c) an organometal compound wherein the metal is selected from the Groups 1-14 of the Periodic Table of the Elements; a supported solid catalyst comprising (a), (b), (c), and (d) a support material, obtainable by combining components (a), (b), (c), and (d) in any order, and wherein during at least one step in the preparation of the solid catalyst, component (a) dissolved in a diluent in which (a) is soluble, is converted into solid form; a method for preparing the solid catalysts; and a process of polymerization using these solid catalysts.
