Thermal Property of Polymers

By changing temperature, crystalline polymers experience the various phase transitions including the phenomena of melting, crystallization, thermal degradation, and so on. The experimental techniques how to measure the thermal behaviors of polymer materials are introduced in a concrete manner. In particular, the details of the differential scanning calorimetric (DSC) method are described, including the modulated-temperature DSC technique. As for the thermomechanical analysis (TMA), the effect of tensile force on the structure and mechanical property of the thermally-activated polymer chains is learned experimentally and theoretically as one typical case study.
