✦ Synopsis

The thermal degradation of poly(viny1 chloride) (PVC) was studied by following the rates of dehydrochlorination a t temperatures between 18OOC and 280°C in pure nitrogen and air flow. Iron oxide accelerates the elimination of hydrogen chloride from PVC. The accelerating effect depends on the concentration of the oxide, and it has a maximum. This work tried to explain these behaviors.

A mechanism of dehydrochlorination is suggested for polymer containing iron oxide.
