摘要：
The process of PVC decomposition has been studied by FTIR under dynamic conditions. The IR spectra have been directly obtained from PVC films pyrolyzed ''in situ'' in a specially designed IR cell. A qualitative description of the changes observed in the spectra is presented. Below 270 degrees C, the only phenomena observed are shifts in the absorption bands involving chlorine atoms. Nevertheless, above this temperature strong modifications of the spectra are observed as a consequence of the changes produced in the structure of the polymer. Characteristic absorption bands of the polymer disappear, whereas several bands corresponding to different vibration modes of C=C bonds appear. (C) 1997 Elsevier Science Ltd.
