Abstract
Polyvinylchloride films were obtained and studied by optical methods after thermolysis. A strong increase in the intensities of the absorption spectra and a shift in the long-wave region with increasing thermolysis time are established. These facts can be explained by the increase in the number and size of the conjugated carbon double bonds. The optical absorption method is sufficiently informative to determine the relative change in the number of conjugated carbon double bonds and their sizes. The amount of conjugated carbon double bonds in polyvinylchloride films is estimated as a function of the thermolysis time. The shift of the absorption spectra to a longer-wavelength region is analyzed with increasing conjugated carbon double bonds with increasing thermolysis time studied.
