摘要：

A series of epoxy resins has been analyzed by measuring their heat capacities from 140 K up to decomposition using differential scanning calorimetry. The data for the solids were compared to the vibrational heat capacities computed using an approximate vibrational spectrum consisting of skeletal heat capacities (based on a Tarasov analysis) and group vibrations (obtained from IR and Raman data). The heat capacities for the liquid were used to construct an addition scheme for the molecules with similar groups in their repeating unit. The glass transition and the melting transition are discussed by analyzing the fast-cooled and well crystallized samples.
