    Abstract

    The dielectric properties of a curing epoxy/amine system have been studied from 25 to 120°C at 2.45 GHz. The epoxy resins at different extents of curing exhibit a γ relaxation, which can be described by the Arrhenius rate law. The relaxation is attributed to the motions of the dipolar groups associated with the crosslinking system. A simple model is proposed to represent the temperature dependence of the dielectric properties. A complete description of the evolution of the parameters during the polymerization has been obtained. The nature of the information yielded by dielectrometry on the dynamics of the system is discussed.
