| Abstract: | A novel bisphenol epoxy resin prepolymer was synthesized by the reaction of 1,1-bis(4-hydroxy-3-methylphenyl) cyclohexane (DMBPC) with epichlorohydrin (ECH) in the presence of sodium hydroxide.The curing behaviors of the epoxy system consisting of 1,1-bis(4-hydroxy-3-methylphenyl)cyclohexane epoxy resin (DMBPCEP) and 4,4'-diaminodiphenylmethane (DDM) as the curing agent were investigated using differential scanning calorimeter ( DSC),and the thermal properties of obtained cured products were examined by DSC,heat distort temperature (HDT) and thermogravimetric analysis (TGA).The water absorption was also compared with that of the bisphenol A epoxy resin (DGEBA).The calculated results from DSC data showed that the value of the activation energy (Ea) and the curing reaction order (n) are 49.8 kJ/mol and 0.87,respectively,and the optimal curing process was determined.DSC,HDT and TGA analyses and the moisture absorption experimental results indicated that the thermal and water absorption properties of this novel epoxy resin are superior to those of DGEBA. |
