摘要：

The initiation of polystyrene photo-oxidation has been studied and the quantum yield of initiation (phi(R)) 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 length of the light and the irradiation conditions (temperature and presence of oxygen).
