Abstract : This report is concerned with showing that certain polymers automatically generate a significant measure of thermal protection on exposure to intense thermal radiation by the following mechanism: (1) the polymer decomposes yielding a gas and compounds containing chromophoric groups; (2) the gas propels the compounds containing chromophoric groups into the region between the polymer and the source of the radiant energy; (3) the compounds containing chromophoric groups vaporize, intercept the thermal photons, and reradiate or dissipate the energy to the air as heat. This constitutes the new approach to protection against intense light energy. (Author)
