Hw. Xie et al., THERMAL-DECOMPOSITION PROCESSES OF SOME E LECTRICALLY CONDUCTING POLYMERS INVESTIGATED BY DIRECT PYROLYSIS MASS-SPECTROMETRY, Huaxue xuebao, 53(2), 1995, pp. 173-177
Thermal decomposition processes of poly(thio-1,4-phenylene) (PPS), pol
ythiophene (PT) and polyaniline (PAn) were investigated by direct pyro
lysis EI or CI mass spectrometry (DPMS). They can provide up to heptem
er pyrolynates and give some structure properties. The results indicat
e that the thermal degradation all undergoes in radical decomposition,
PPS pyrolyzes into linear and cyclic oligmers, but PT and PAn pyrolyz
e only into linear oligmers.
