The methyl groups of poly(2,6-dimethyl-l,4-phenylene oxide) (PPO) were brominated to various extents. Bromobenzylated PPO (BrPPO) samples with degrees of bromination of 16, 37, 50, 69 and 76% were found to be miscible with polystyrene (PS) but BrPPO with a degree of bomination of 92% was immiscible

The thermal oxidation and photo-oxidation of poly(2,6-dimethyl-l,4phenylene oxide) have been examined. Oxidation of the plastic results in the evolution of carbon dioxide, nitrogen and traces of hydrogen, the introduction of considerable crosslinking, and increased absorption in the hydroxyl and car
