Abstract
An improved process for the homopolymerization and copolymerization of .alpha.-olefins utilizing highly dilute .alpha.-olefin feedstreams to effect high conversions and catalyst efficiencies in the production of non-ethylene copolymers. The instant invention is particularly adaptable to polymerizing the .alpha.-olefin content of commercially available refinery feedstreams such as Raffinate-2.
