Abstract
The dielectric behavior of an epoxide/ethylenediamine formulation has been studied during cross‐linking in the frequency range 103−1010 Hz at 25°C and 70°C. Dielectric data were collected both in the frequency and in the time domains and analyzed in terms of a combination of two Havriliak‐Negami functions. A complete description of the evolution of the relaxation parameters during the reaction was obtained. The nature of the information yielded by dielectrometry on the dynamics of the system is discussed. © 1995 John Wiley & Sons, Inc.Keywords
