The thermal response of several test materials was characterized by isothermaland dynamic thermogravimetric analysis. Pyrolysis gas analysis, infrared spectra analysis and elemental analysis were employed also to formulate a description of the thermal-degradation reaction. A new, systematic approach to the determination from dynamic TGA data of kinetic parameters describing pyrolysis was developed. Samples of linear para-polyphenylene, polybenzimidazole,polyimide, phenylated polyquinoxaline and phenolic resins were tested.
