Paper doi abstract bibtex Dielectric measurements have been performed on unsaturated polyester resins, cured with different styrene contents. Based on the random walk model (RWM), we have determined, as a function of the styrene content, the width of the density of states kT0, the average energy barrier height 〈EA〉 that a structural unit must crossover in order to relax, the fragility index α and the value of Tc at which qualitative changes in the dynamics occur. The RWM data are in good agreement with the strong-fragile concept.
