摘要：

The main alpha and sub beta relaxations in bisphenol A-based epoxides cured by two kinds of aliphatic diamines were examined in wide temperature and frequency ranges by using middle-frequency dynamic, dielectric, and ultrasonic measuring systems. The obtained temperature-frequency correlation maps revealed an Arrhenius-type behavior for the beta relaxation with apparent activation energy of 16 kcal/mol. For the alpha relaxation, the maps were in good agreement with the W.L.F. equation. Owing to the similarity of structure in these resins, both maps showed the same tendencies.
