Abstract

Separation of volatile components from the polymer melts formed during the homopolymerization of ethylene or the copolymerization of ethylene with other copolymerizable compounds at elevated pressures and elevated temperatures by countercurrent treatment with ethylene. Superior separations are obtained by the process.
