A Statistical Approach Authors: Marcos Perez University of... WitrynaThese predicted glass transition temperatures are compared to experimental T g values as obtained from differential scanning calorimetry measurements. As expected, the predicted values are systematically higher than the experimental ones (about 12−34 K) as the cooling rates of the modeling methods are about a factor of 10 12 faster.
