Advanced AC calorimetry of polycaprolactone in melting region

摘要: Abstract The new capabilities of AC calorimetry, when working at frequencies above the classical limit were demonstrated. appropriate frequency range calorimetry was substantially enlarged. It shown that advanced can be applied for studying dynamic heat capacity polymers in 0.1–1 Hz. Thus, processes with characteristic time as short ca. 5 s registered. technique investigation melting kinetics polycaprolactone. found polycaprolactone is related to an activated process. activation process after a step heating described by stretched exponent and decay only one times. dependencies on temperature thermal treatment investigated 0.1–1Hz modulation amplitudes 0.005–0.2 K.
