Description

ABSTRACT OF THE DISCLOSURE Removal of dissolved vanadium catalyst residues from ? -olefin polymer solutions improves the heat stability of the polymer recovered therefrom. Vanadium residues are removed from ?-olefin polymer solutions in inert solvents by contacting the solutions at 50-225°C. with one or more active metals, either in their elemental form or as alloys, selected from alkali metals, aluminum, and zinc, and separating the solutions from vanadium residues precipit- ated thereby. The process can be carried out continuously by passing the polymer solution through a column containing the active metal.
