POLYMERIZATION CATALYST SYSTEMS, THEIR PRODUCTION AND USE

摘要

This invention is generally directed toward a supported catalyst system usef ul for polymerizing olefins. The method for supporting the catalyst system of the invention provides for a supported bulky ligand transition metal catalyst system which when utilized in a polymerization process substantially reduces the reactor fouling and sheeting particularly in a gas phase polymerization process. The method comprises contacting a porous support with a metallocene solution and an activator solution, wherein the total volume of the metallocene solution and the activator solution together is in the range of from less than that at which a slurry is formed to above one time the total pore volume of the porous support.
