摘要：

A fundamentally new procedure was proposed for evaluating the parameters of plasticizer desorption from flexible-PVC compounds by quantitative description in terms of a developed kinetic model and of TGA data obtained under the conditions of a linear rise in temperature up to the onset of chemical transformation. The obtained estimates were shown to satisfactorily describe the desorption of a plasticizer from PVC cables in the course of their actual long-term (longer than ten years) service. The method proposed makes it possible to shorten the duration of testing from several months to 1-2 days.
