Plasticizer migration from poly(vinyl chloride) remains a critical problem due to the high consumption of this polymer in a flexible form. The systems poly(vinyl chloride) (PVC)/labeled dioctyl phthalate (DOP)/white spirit, kerosene, white oil, or lubricating oil have been considered in this article. Migration experiments were carried out at three different temperatures (30, 50, and 70°C) for extremely prolonged periods of time. At the initial stages the data collected fit well to short-term Fickian behavior. The respective diffusion coefficients increase with temperature, conforming also to an Arrhenius form, but the eventually obtained migration values seem to pass through a minimum in the case of the lighter oils.
