The initiation of polystyrene photo-oxidation has been studied and the quantum yield of initiation (~PR') for u.v.-irradiation at 315 K in the presence of atmospheric oxygen has been found to be 10 -3. Using ESR spectra, five distinct free radicals have been found; their nature depends on the wave l

Aromatic ketones have been used to initiate the photo-oxidation of polystyrene at wavelengths > 300 nm. Quantum yields of oxygen absorption have been measured. The results indicate that only ketones with a lowest 3(n it\*) state are efficient and that hydrogen abstraction is the initial step of the
