IR-spectroscopic study of the condensation products of heat-degradation of polyethylene and polypropylene in inert atmosphere
Collection of Czechoslovak Chemical Communications1990Vol. 55(9), pp. 2233–2243
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.
