Abstract The epoxy resin (EMBHBC) of (2E,6E)-bis (4-hydroxybenzylidene)-4-methyl cyclohexanone
(MBHBC) was synthesized by condensing 0.5 mol MBHBC and 2.5 mol epichlorohydrin in 500
mL isopropyl alcohol as a solvent and 1.0 mol NaOH in 50 mL water as a catalyst at 80°C for 3 h.
The structure of EMBHBC was supported by UV-Vis, FTIR, 1
HNMR and 13CNMR spectroscopic
techniques. Molecular weights and molecular weight distribution of EMBHBC were determined
by gel permeation chromatography. DSC thermogram of EMBHC showed one endothermic
transition (95.9°C) and two exothermic transitions (317.7°C and 382.2°C) due to melting and
decomposition transitions, respectively. More >
