Abstract
A statistical model of dehydrochlorination of PVC in inert atmosphere based on zip mechanism has been suggested. A good agreement has been found between experimental and theoretical curves of the dehydrochlorination carried out to high conversion degrees. Mathematical evaluation gives the activation energy and the frequency factor of the random splitting off of HCl from PVC: Ea = 170 kJ mol-1, log (A/s-1) = 12.9 (independent of the PVC type).
