ABSTRACT:
A process of forming self-condensation products of a phenol under polymer-forming reaction conditions which comprises contacting a phenol with oxygen in the presence of a secondary aliphatic amine and an effective manganese chelate complex is described. The resulting polyphenylene oxide resins in combination with styrene resins provide thermoplastic compositions having improved impact strength.
