Abstract

The main α and sub β 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 β relaxation with apparent activation energy of 16 kcal/mol. For the α 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. © 1993 John Wiley & Sons, Inc.
