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