Abstract
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.
