摘要：

The dielectric behavior of an epoxide/ethylenediamine formulation has been studied during cross-linking in the frequency range 10(3)-10(10) Hz at 25 degrees C and 70 degrees 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. (C) 1995 John Wiley & Sons, Inc.
