ABSTRACT:
A process is provided comprising copolymerizing, under copolymerizing conditions, ethylene with one or more alpha-olefins, using a catalyst system, where said catalyst system has been sized, to produce a lower-density-copolymer, where said lower-density-copolymer has a density lower than a similar copolymer produced by copolymerizing, under said copolymerizing conditions, ethylene with said one or more alpha-olefins, using said catalyst system, where said catalyst system has not been sized, where said catalyst system that has been sized has had substantially all particles removed that produce, under said copolymerizing conditions, a higher-density-copolymer, where said higher-density-copolymer has a density higher than said similar copolymer.
