摘要：

The thermal degradation of polyvinylchloride (PVC) and PVC in the presence of ZnCl2 was studied using UV-visible spectroscopy. Formation of a charge transfer complex, H+ZnCl3-, with the conjugated chain was observed. The results are compared with the previous studies at low temperature. Time dependence of concentration of polyene sequences in the presence of different amounts of ZnCl2 was also studied. A critical analysis of the measurement of polyene sequences and the effect of ZnCl2 on their formation has been given.
