Abstract
Oxidation studies from 425 to 600 °C of porous carbons obtained from the pyrolytic decomposition of pure polyvinylidene chloride have been carried out in static oxygen systems. Measurements of weight change were made by means of a sensitive thermal microbalance. Empirical activation energies for the oxidation reaction were determined to be approximately 1 eV in magnitude, and comparison is made with previously published results for graphite. Carbon samples obtained from polymers compressed at different molding pressures showed somewhat different temperature and pressure rate dependence. An unusual pressure dependence was observed for the rate of reaction, and a tentative explanation is offered.
