Abstract: | Thermal decomposition of polyurethane, epoxy, poly(diallyl phthalate), polycarbonate, and poly(phenylene sulfide) was examined
using a combination of thermal and chemical analysis techniques. Thermal gravimetric analysis with simultaneous analysis of
evolved gases by Fourier transform infrared spectroscopy, differential scanning calorimetry, and gas chromatography coupled
with Fourier transform infrared spectroscopy were used to obtain rate data, determine enthalpy changes, and identify decomposition
products. Examination of the evolved decomposition products indicated a common set of chain scission mechanisms involving
the aromatic moieties in each of the polymer materials studied. |
