Abstract
Dynamic heat capacity of at-polypropylene has been measured around the glass transition temperature. The dynamic heat capacity vs temperature curve shifted to higher temperature as the frequency of the periodic heating increased. The activation energy was estimated as 77kcal/mol from the Arrhenius plot. It was found by comparing the results from the thick sample and the thin sample that the thermal conductivity does not exhibit anomalous behavior around the glass transition temperature.
