dc.description.abstractThe relaxation spectrum of poly(dicyclohexyl itaconate) (PDCHI) was studied by dynamic mechanical, DC dielectric and thermally stimulated current measurements. Four relaxations, alpha, beta, gamma and delta, were obtained. The only method by which all four peaks were observed is that of dynamic dielectric measurements because of the broad range of frequencies employed. The beta, gamma and delta-relaxations were characterized by the activation energy in a relaxation map. A tentative explanation of the molecular origin of each absorption is proposed. In the case of thc alpha-relaxation we have used two transformations, one from the permittivity to polarizability and thc second from compliance to deformability in order to make evident the existence of this relaxation.
