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. The invention is more particularly drawn to a gas phase polymerization process for polymerizing one or more olefin(s) in the presence of a metallocene catalyst system in a fluidized bed reactor in the absence of or with a low mount of a scavenger.
