DEGRADATION OF HALOPOLYMERS BY EXPOSURE TO HIGH-INTENSITY THERMAL PULSES
Abstract
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 halogen/hydrogen 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.
