## Abstract A set of poly(vinyl chloride) samples were investigated with respect to their thermal stability. The dehydrochlorination rates were measured in nitrogen at 190Β°C by use of a very accurate, conductometric method. For all polymers studied, a significant molecular weight increase was obser
The thermal degradation of poly(viny1 chloride) (PVC) was studied by following the rates of dehydrochlorination a t temperatures between 18OOC and 280Β°C in pure nitrogen and air flow. Iron oxide accelerates the elimination of hydrogen chloride from PVC. The accelerating effect depends on the concent
