The thermal degradation of aromatic polyimides in nitrogen at 700°C was studied using pyrolysis gas chromatography, infrared spectroscopy, and radiochemical techniques. Degradation mechanisms were postulated to account for the breakdown products found and to explain variations in the ratio of carbon monoxide to carbon dioxide.
