The second heating curves of DSC thermograms for PEVAs at a temperature range of −100 °C to 150 °C (a) and cPEVAs determined between −100 °C and 200 °C (b) with a heating rate of 20 C·min⁻¹, where the melting temperature (T_m) was obtained as the endothermic peak maximum in the heating curve and the glass transition temperature (T_g) was shown as a step-wise transition in the thermograms, partly overlapped with the melting peak. The first cooling step of DSC thermograms for PEVAs with a temperature range of −100 °C to 150 °C (c) and cPEVAs determined in the temperature range between −100 °C and 200 °C (d) with a cooling rate of 20 C·min⁻¹, where the crystallization temperature (T_c) was determined as the peak maximum.
