A method is presented for the estimation of kinetic parameters during polymer degradation from two DTA traces. By this method, changes in mechanism with conversion may be detected. The method is applied to polyethylene, polypropylene, polystyrene, and polytetrafluoroethylene (Teflon). The agreement between observed and reported values of kinetic parameters is good. Advantages and disadvantages of the method are discussed.
