heal.abstract	Ultra-violet (u.v.) irradiation of poly(vinyl chloride) (PVC) sheets is a well known technique for inducing surface crosslinking in order to prevent plasticizer migration phenomena. Accordingly, for varying u.v. irradiation doses, long-term migration data obtained by radioactivity measurements are presented for the systems PVC/labelled dioctyl phthalate (DOP)/methanol, ethanol, n-propanol and n-butanol. Even at the higher doses examined, migration was found to be only moderately hindered; primary kinetics studies also yielded similar results to those already established for untreated material. This behaviour was attributed mainly to counderdiffusion processes resulting in progressive failure of the protective surface layer developed during irradiation. © 1986.	en
