Chalcone based epoxy resin (EBHBC) of (2E, 6E)- bis(4-hydroxybenzylidene) cyclohexanone
(BHBC) was synthesized by condensing 0.5 mol BHBC and 2.5 mol epichlorohydrin in
500 mL isopropanol as a solvent and 1.0 mol NaOH in 50 mL water as a catalyst at 80o
C. The
structure of EBHBC is supported by spectral techniques. Molecular weights and molecular
weight distribution of EBHBC were determined by gel permeation chromatography. DSC
thermogram of EBHC showed one endothermic transition (146.1°C) and two endothermic
transitions (253.52°C and 397.34°C) due to melting, some physical change and decomposition
transitions, respectively. EBHBC is thermally stable up to about 300o
C and followed two step
degradation reactions. First step involved 21.2% weight loss over 300-390o
C with temperature
of maximum weight loss at 382°C. Similarly second step involved 39% weight loss over 390-
555°C with temperature of maximum weight loss at 418°C.
