Abstract

Temperature modulated differential scanning calorimetry (TMDSC) data are simulated through the glass transition region using the Tool-Narayanaswamy-Moynihan (TNM) model of structural recovery. The simulated data are analyzed using a fast Fourier transform similar to conventional Temperature-modulated differential scanning calorimetry techniques. The glass transition temperature (T_g) and enthalpy of aging (ΔH_a) were calculated from the simulated data and compared with the values expected based on linear isothermal simulations for the case of the glass temperature and based on the input simulated data for ΔH_a. The errors associated with the TMDSC data analysis were thus quantified.
