Vitrification effect on the curing reaction of epoxy resin

The curing reaction of diglycidyl ether of Bisphenol A(DGEBA) with triethylene tetramine(TETA) was studied by differential scanning calorimetry (DSC). The reaction was affected as the vitrification occurred when the glass transition temperature (T sub g ) of the reaction mixture exceeded tha curing...

Summary:The curing reaction of diglycidyl ether of Bisphenol A(DGEBA) with triethylene tetramine(TETA) was studied by differential scanning calorimetry (DSC). The reaction was affected as the vitrification occurred when the glass transition temperature (T sub g ) of the reaction mixture exceeded tha curing temperature. In order to describe the curing reaction in the rubbery state as well as in the glassy state, the reaction kinetic equation containing the generalized WLF equation term was proposed and the parameters were determined from the DSC data. 22 ref.--AA
