The different transitions and reactions involved in the thermal processing of ternary ethylene vinyl acetate (EVA)-polyethylene (PE)-azodicarbonamide (ADC) mixtures with different concentrations of PE and ADC; which was used as a foaming agent; were studied by means of differential scanning calorimetry. The effect of the concentration of PE in the ternary samples was practically linear; which showed an increase in the fusion heat of the PE and the PE domains of the EVA. On the contrary; the mechanism of the thermal decomposition of ADC that the ternary mixtures contained was strongly dependent on its concentration in the sample; which showed clear deviations from linearity. © 2008 Wiley Periodicals; Inc;
