Measurements have been performed on poly(ethylene terephthalate)glycol/montmorillonite nanocomposites with different filler contents using differential scanning calorimetry (DSC) and temperature modulated differential scanning calorimetry (TMDSC). According to the strong-fragile concept proposed by Angell, we have determined the values of the fragility index m. In a second time, we have calculated the average size of a cooperative rearranging region (CRR) z(Tg) at the glass transition according to the definition proposed by Solunov. However, z(Tg is a dimensionless quantity and then only allows a comparative study between different samples. To calculate the average number of monomer units by CRR noted Nα, we have used the method developed by Donth. The results show that the presence of montmorillonite in PETg matrice implies modifications on structural relaxation phenomena. Furthermore, we have shown that z(Tg and Nα values have the same evolution in function of filler content.
