Formation of dioxins in thermal degradation of poly(vinyl chloride)-based polymer composites

It was shown that the composition of PVC-based composites influences the composition of combustion gas products. For the pure PVC, the conditions of thermal degradation that allow thermal oxidation and pyrolysis to be distinguished were determined. The composition of products arising from the thermal degradation of a plasticizer, dibutyl phthalate, was examined. Thermodynamic functions for the formation of dibenzo-dioxins and dibenzofurans from phthalates were calculated.
