Application of Inorganic Compounds at the Thermal Processing of Polyvinylchloride

A review of publications on the effect of various inorganic additives (metals oxides, hydroxides, chlorides and carbonates) oil the process of dehydrochlorination and pyrolysis at the thermal processing of polyvinyl chloride (PVC). A decrease in temperature of the PVC dehydrochlorination step is noted at processing in the presence of chromium, iron, cobalt, copper and molybdenum oxides. Aluminum, titanium, circonium, cerium and lead oxides do not change temperature of beginning of PVC destruction. No effect noted of the oxides at the second step of PVC destruction.
