Abstract
Thermal degradation of aromatic polyesters 1 (m = 2 , 3 , 4 , 5 , and 6) was studied by pyrolysis/gas chromatography using a Curie-point pyrolyzer directly attached to a gas chromatograph with a thermally stable polar separation column (Thermon-1000) to cover a wide range of the degradation products. The characteristic peaks appearing on the pyrograms were identified using a mass spectrometer with a chemical ionization source which was also directly attached to the gas chromatograph. On the basis of the observed pyrograms, the common degradation mechanisms of the aromatic polyesters were discussed.Keywords
