Abstract
Infrared spectra were measured of condensates generated by heating polyamide-6, polyamide-12, polyamide-11, polyamide-8 and polyamide-6,6 in inert atmosphere at 300, 350, 400, 500, and 600°C for various time. The products of thermal degradation were characterized by infrared spectroscopy. It was found that the thermal history of polyamide degradation can be detected from infrared spectra.
