Trans-1,4-Polybutadiene (TPBD) transforms a crystal structure at the temperature of heat storage. In this study, the molecular structure of TPBD was measured using the Raman spectroscopy. The measurement of the amount of heat storage of TPBD was performed using a differential scanning calorimetry. It is found that there is a correlation between the amount of heat storage and the change of C-H bond by auto-oxidation. A thermal cycle test was carried out to obtain the change of heat storage and release amount of TPBD. The heat storage and release amount was calculated from the obtained temperature history. The heat storage amount became between 60 J/g and 90 J/g. The heat release amount became between -70 J/g and -100 J/g. It is verified that the amount of heat storage of TPBD does not deteriorate during 1700 cycles.
