Dynamic thermal methods of analysis are becoming increasingly important for polymer characterization. These techniques are based on measuring changes in certain physical properties continuously and automatically upon variation of the sample temperature. This presentation reviews thermal analysis in general, and briefly describes the features and applications of several commonly used thermal methods, such as differential thermal analysis, differential scanning calorimetry, thermogravimetry, thermomechanical analysis, electrothermal analysis, thermo-optical analysis, and thermal evolution analysis. General references are given for the various techniques.
