ResumoAn empirical corresponding states relationship between the ratio of the heat capacities Cp/Cv of polymers and the reduced temperature T/Tg has been found. This relationship is discussed in terms of corresponding states behavior. This relationship is significant and useful in that the ratio Cp/Cv is a fundamental quantity for a solid polymer and a knowledge of the value of this ratio is useful for converting adiabatic data into the corresponding isothermal values and vice versa.
