Poly(vinyl chloride) film shows substantial changes in its photoacoustic absorption spectra (PAS) on either irradiation or heating in the presence of O 2 or N 2 . These spectral changes are due to the conjugation structures and carbonyl (group formation), formed during photo and thermal degradation. In this paper interpretations of the PAS and of the decomposition mechanism of PVC are presented.
