Abstract : The thermal degradation of halo-polymers was studied in relationship to possible processes of thermal protection. The kinetics and energetics of the thermal degradation of polyethylene, polyvinyl fluoride, polyvinylidene fluoride, polyvinyltrifluoroethylene, polytetrafloroethylene, polyvinyl chloride, and polyvinylidene chlorofluoride, were investigated by thermogravimetric analysis (TGA) and differential thermal analysis (DTA). It was concluded that energy absorption of endothermic decomposition is not a major factor in the thermal protection afforded by these polymers, nor does endothermic decmposition polymers. Theoretical and experimental studies were made to relate smoke formation of thermal protection. The results support, but do not prove, the decomposition of a materials is a significant factor in the protection afforded against high intensity thermal radiation. (Author-PL)
