We present the results of a theoretical study and put forward a novel mechanism for the photodegradation of the polymer poly(2,6-dimethyl-l,4-phenylene oxide) (PPE). The primary step is a 1,5-hydrogen transfer from the methyl group of one ring system to the ipso-earbon of the adjacent monorneric uni
