Abstract

This invention is generally directed toward a supported catalyst system useful for polymerizing olefins. The method for supporting the catalyst of the invention provides for a supported bulky ligand transition metal catalyst which when utilized in a polymerication process substantially reduces the reactor fouling and sheeting in a gas, slurry or liquid pool polymerization process.
