differential scanning calorimetry. Analytical method that independently measures the rate of heat flow to a sample against a reference standard of the same temperature. Data are obtained by monitoring the differential heat flow as a function of temperature. DSC can measure heat capacities, phase transitions, dehydration, and decomposition reactions.
Differential Scanning Calorimetry. In DSC the sample and a reference material are heated and cooled in a defined manner. DSC provides a rapid method for the determination of the temperature profile of a polymeric material. This includes e.g. measurement of heat capacity, specific heat, melting, crystallisation and glass transition temperatures, heat (enthalpy) of fusion, crystallization, study of thermal stability or reaction kinetics and in certain cases identification of the polymer or polymer mixture.
