The study was conducted to 1 determine whether high molecular weight, high oxygen containing inorganic additives can be effectively used in developing nonleachable flame retardants for self-help application to existing roofs, 2 investigate the kinetics and thermal decomposition of cotton and synthetic polymers, and 3 modify the Parker-Lipska P-L model to more closely predict the empirical increase in char yield in retardant treated cellulosics. The sprayed-on, interstitially precipitated ammonium phosphomolybdate, ammonium phosphotungstate, and magnesium ammonium phosphate afford seasonal no more than 30 inches of rain protection againstfirebrands. Similarities in the weight-loss kinetics and products of pyrolysis of cotton and wood-derived cellulose suggest that the guidelines used in the P-L model in chooding retardants might be applied to all cellulosic materials.
