摘要： 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 metallocene catalyst which when utilized in a polymerization process substantially reduces reactor fouling and sheeting in a gas or slurry polymerization process.

摘要： The present invention relates to a continuous process for the polymerization of olefin(s) utilizing a metallocene catalyst or catalyst system in a continuous slurry or gas phase polymerization process for polymerizing monomer(s). The invention is more particularly drawn to a gas phase polymerization process for polymerizing one or more olefin(s), alone or in combination, in the presence of a metallocene catalyst system in a fluidized bed reactor, preferably operating in a condensed mode.
