Method for fractioning poly (ethylene oxide) formed using a metallic cyanide catalyst

This invention relates to methods for purifying poly(ethylene oxide) polymers. A poly(ethylene oxide) polymer having low and high molecular weight fractions is fractionated by dissolving the polymer in a solvent for the low molecular weight fraction. A good separation of the low and high molecular w...
