Polaron Mechanism in the Thermal Degradation and Stabilization of Poly(Vinyl Chloride)

The mechanism of degradation of poly(vinyl chloride) (PVC) has long been a matter of discussion. Some excellent reviews have been published [1–4]. Over the years, different investigators have contributed to the discussion of the three main mechanisms concerning polyene propagation in the thermal dehydrochlorination (DHC) of PVC.
