Patent ID: 8163854

Claim:
A polymerization process comprising contacting one or more monomers polymerizable by coordination polymerization under suitable polymerization conditions with a polymerization catalyst formed by a method comprising: reacting a metal oxide support, selected from the group consisting of: silica, fumed silica, alumina, silica-alumina, magnesia, titania, zirconia, montmorillonite, phyllosilicate, zeolites, talc, clays, silica-chromium, silica-titania, aerogels, spherulites, and mixtures thereof, with at least one silane compound having the general formula: H x Si(R) 4-x , wherein x is at least 1; and R is a hydrido, alkyl, aryl, heteroalkyl, or heteroaryl ligand, in the presence of a first Lewis acid, thereby generating a silyl capped support; reacting said silyl capped support with a second Lewis acid, which may be the same or different as said first Lewis acid, and an amine, thereby forming a supported silyl-capped silica-bound anion activator; and reacting said supported silyl-capped silica-bound anion activator with at least one catalyst precursor, thereby forming said polymerization catalyst.
