Abstract:
A method for the purification of aromatic polyether polymers prepared by a halide displacement polymerization process comprises adsorbing the catalyst with an alkali metal halide to form an adsorbent component and then removing the adsorbent component. Mixtures resulting from this method are also discussed.
