The surface photooxidation of poly(ethylene terephthalate) (PET) and poly(vinyl chloride) (PVC) has been studied by ESCA in the presence of Leucopur EGM as brightener. The results indicate that in the case of PVC there is no effect of the additive in the photooxidation, while in the case of additivated PET it is possible to observe surface protection for the higher concentrations of brightener used.
