Abstract
The curing of epoxy resin of (2E, 6E)-2,6-bis(4-hydroxy benzylidene) cyclohexanone (EBHBC)
was carried out at four different heating rates in the nitrogen atmosphere by using 4,4’-diamino
diphenylmethane (DDM), 4,4’-diamino diphenyl sulfone (DDS), and 1,2,3,6-tetrahydrophthalic
anhydride (THPA) as hardeners. From DSC curves onset, peak exotherm and end set
temperatures, as well as heat release, were derived. The energy of activation was derived
following Kissinger and Ozawa methods. Observed trend in Ea is EBHBC-THPA > EBHBCDDS > EBHBC-DDM > EBHBC. Nature and chemical structure of the hardeners affected the
curing of EBHBC.
