Abstract

This work presents new results concerning characterization of polymethyl(α-n-pentyl)acrylate polymer by means of thermal analysis. In differential scanning calorimetry investigations, the measured values of T g, T f and ΔC p, i.e. the glass transition temperature, the fictive temperature and the heat capacity step at T g, show that the polymer can be considered as fragile. Thermogravimetric analysis revealed two mass losses, the first, at low temperature, being associated with the evaporation of water molecules, and the second, at high temperature, corresponding degradation of the polymer. This degradation is a two-step phenomenon. Finally, study of the β and the α transitions by elementary and complex TSDC led to the following values: T β=−40°C, T α=36°C, T c=47°C, τc=2.5 s and ΔH=85 to 165 kJ mol−1.
