Agricultural PVC film containing PVC 65 %, DOP (dioctyl phthalate) 32 % as plasticizer, Ca-Zn stearates and surface active agent was treated at 150-250°C in 0-7 M NaOH solutions (1 M=1 mol dm-3) for 0-12 h, in order to study the kinetics of the dehydrochlorination. The degree of dehydrochlorination was increased as the temperature and reaction time were high and long. The dehydrochlorination was reached maximum in 3 M NaOH and declined over 3 M NaOH. The dehydrochlorination was increased rapidly higher than 200°C, and reached ca. 100 % at 250°C over 5 h. The dehydrochlorination progressed in first order kinetics and the apparent activation energy was 30 kcal/mol.
