✦ Synopsis

Absorption spectra of thermally degraded PVC films are recorded for a number of polymer samples submitted to various dehydrochlorination conditions and in the presence of stabilizers. Correlations are drawn between colour in degraded PVC and dehydrochlorination; the spectra are also discussed qualitatively with special reference to stabilization. The average polyene sequence length in degraded PVC is calculated using an ozonization technique and compared with values derived from peroxide data and from absorption spectra.

The presence of dicumyl peroxide, benzoyl peroxide, cumene hydroperoxide or azobisisobutyronitrile in PVC leads to increased dehydrochlorination at 150 ° in nitrogen. Hydroperoxide groups introduced during ozonization of degraded PVC have similar effects on the thermal stability of PVC but attempts
