Abstract
Infrared spectra of condensates generated by heating of polyethylene and polypropylene in inert atmosphere for various times at 300, 400, 500 and 600 °C were measured. The condensed products were characterized by means of infrared spectra. It was found that IR-spectra are suitable for determining the thermal history of polyethylene and polypropylene degradation.Keywords
