Abstract Bisphenol-C epoxy crotonate resin was synthesized by reacting 8.09g epoxy resin of bisphenolC, and 2.15g crotonic acid using 25 mL 1,4-dioxane as a solvent, and 1 mL triethylamine as a
catalyst at reflux temperature for 1-6 h. Solid epoxy crotonate (ECCR) is highly soluble in
common organic solvents. ECCR was characterized by its acid (24.5-1.5 mg KOH/g) and hydroxyl
(504.5-678.4 mg KOH/g) values. The structure of ECCR is supported by FTIR and 1
HNMR
spectroscopic methods. A DSC endothermic transition at 229o
C indicated melting followed by
thermal polymerization of ECCR. ECCR is thermally stable… More >
