Influence of metal oxide on the fixation of chlorine in thermal decomposition of poly (vinylidene chloride co vinyl chloride)

Abstract

The chlorine-fixation ability of various metal oxides (ZnO, Fe 2O3, La2O3, Nd2O 3, CaO) has been examined in thermal decomposition of copolymer of poly(vinylidene chloride) and poly(vinyl chloride), denoted hereafter as PVDCcp, at 1073 K under inert atmosphere. The addition of metal oxide gives rise to the suppression of HCl gas owing to the chlorination of oxides. The formation of main chlorinated organic compounds in the process of thermal decomposition has also been investigated for the mixture of the PVDCcp and metal oxides.
