The thermal dehydrochlorination of PVC has been examined on some samples prepared by fractionation of a commercial PVC, and some other samples obtained by polymerization at different temperatures. The results disagree with the concept of a continuous dehydrochlorination from one side to the other of
The dehydrochlorination of a syndiotacticityenriched poly(viny1 chloride) (s-PVC) gave polyene materials and the structure and properties of dehydrochlorinated specimens were studied. The results were compared with those obtained for polyene materials formed from a commercial poly(viny1 chloride) (c
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
