Four series of halopolymers were exposed to high-intensity thermal energy pulses in a carbon arc-image furnace. By means of a closed-cell technique, the thermal degradation products were collected and then analyzed by gas chromatographic procedures. Data were also obtained on the ignition and energy-dissipating characteristics of the halopolymers. The results indicate that the ignition characteristics can be qualitatively predicted from the ratio of halogen to hydrogen atoms in the polymer the energy-dissipating characteristics do not depend entirely on the halogen content of the polymers and are not related to their halogenhydrogen ratios copolymers can be synthesized to have low ignition frequencies and also good energy-dissipating characteristics and, as the time of exposure to the thermal energy pulse increases, the nature of the mixture of gaseous thermal degradation products changes and new products appear in the mixture.
