Summary edit

Description
Français : Schéma réactionnel : poly[oxy-(2,6-diméthyl-1,4-phénylène)] [poly(oxyde de phénylène), PPO] obtenu par polycondensation oxydante du 2,6-xylénol en présence d'un complexe catalytique sel de cuivre(I)-amine et de dioxygène.

Cu2Cl2 (CuCl) est le chlorure de cuivre(I) ; l'amine représentée est la pyridine.

Il se forme aussi par dimérisation une faible quantité de diphénoquinone (sous-produit non désiré).
English: Reaction scheme: poly(2,6-dimethyl-1,4-phenylene oxide) (polyphenylene oxide, PPO) obtained by the oxidative polycondensation on 2,6-xylenol (2,6-dimethylphenol, DMP) in the presence of a copper(I) salt-amine complex catalyst and oxygen. Amine shown is pyridine. A small amount of undesired diphenoquinone forms by dimerization.
