Abstract 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… More >
