The relaxation kinetics of the epoxy network diglycidyl ether of bisphenol A (n = 0) and iii-xylylenediamine were studied with differential scanning calorimetry experimental data with a shift peak model. Nonlinear parameters were calculated with aging experiments. The nonexponential parameter and the apparent activation energy were found from intrinsic cycles. Adam-Gibbs theory was used to provide a molecular interpretation based on the enthalpy relaxation. Different assumptions of the variation of specific heat capacity (c(p)) were used to determine the macroscopic molar configurational entropy of the system. (c) 2005 Wiley Periodicals, Inc.
