Description

ABSTRACT:
A process of forming a quinone-coupled polyphenylene oxide is described which comprises contacting a polyphenylene oxide, wherein said contacting is carried out with a quinone in the substantial absence of any monophenol reactant and any active oxidative coupling catalyst system. The resulting new polymers have improved color and in combination with styrene resins provide thermoplastic compositions having improved chemical and physical properties.
