Abstract
Plasticizer migration from flexible poly(vinyl chloride) comprises an important aspect, especially when packaging
foodstuffs and pharmaceuticals. Much of the published work has been intended either to correlate migration into
simulants with that into foods or to study migration into simpler extractants, enabling the various parameters involved
in migration to be studied in isolation. According to the latter approach, the migration of dioctyl phthalate into
petroleum oils has been studied already in our laboratory and in this paper results are presented in an attempt to
reduce or prevent migration by u.v. irradiation. The effect of irradiation time on short and long-term migration
behavior was examined together with the influence of the immersion temperature. The nature of the liquid
environment seemed to be a predominant aspect: high viscosity oils presented a satisfactory behavior in contrast
with those of lower viscosity in which the prevention effect was rather negligible. On the other hand, primary kinetics
studies yielded similar results with those already established for untreated material (i.e., good conformity to the short
time Fickian approximation).

Surface modification of medical PVC by remote oxygen plasma has been studied: surface structure and performance
of treated material are analyzed by weight loss rate, contact angle measurement and XPS. With the increase of
sample distance from the plasma source, weight loss rate drops, electrons and ions and etching action are
restrained; and C=O groups are found in the treated PVC surface. The surface wettability of PVC film can be
improved by remote low-temperature plasma and the radical reaction is intensified.
