Prediction of polymer degradation kinetics at moderate temperatures from tga measurements

摘要

AbstractThermal degradation under vacuum, as measured by weight loss of polymer, has been studied for a variety of polymers and composites. Small‐sample (∼10 mg) TGA studies have been made on polymeric materials. Isothermal studies, at much lower temperatures, have been made on the same materials of much larger size and weight (4–6 g). Comparison of the results shows that TGA can accurately predict the isothermal kin
