heal.abstract	Plasticized poly(vinyl chloride) (PVC) sheets were irradiated with ultra-violet light before immersion in petroleum oils to prevent plasticizer migration and counterdiffusion effects. The penetration of the liquid environment into the sheets was monitored as a function of immersion time at different irradiation levels and immersion temperatures. White spirit and kerosene penetration passes through a distinct maximum with increasing immersion time, suggesting a two-step phenomenon with liquid transfer into and out of the PVC specimens. Nevertheless, in agreement with previous experimental results on plasticizer migration behaviour, the ultra-violet treatment followed appears encouraging: the maximum penetration values do not vary significantly with irradiation time, but the equilibrium values eventually attained are positively influenced, presenting a decrease often close to 50%. © 1990.	en
