Abstract: The kinetics of dehydrochlorination of PVC  from the view-point of the step-by-step model of elimination of the mols. of HCl from the macromols. of polymer is discussed. A differential equation was put forward for the step-by-step model under defined conditions. This equation makes possible to obtain a differential equation which is formally identical with a rate equation of the first-order reactions of dehydrochlorination of model substances contg. only one chlorine atom. The correlation of the solns. of the system of differential equations for individual kinetic steps with the exptl. kinetic curve shows the discrete distribution function of rate consts. by means of which the mean values of rate consts. may be detd. for different samples of PVC.
