High Char Yielding Nitrosubstituted Epoxide Resins,
Abstract
The thermal properties of a number of nitrosubstituted and analogous nonnitrosubstituted epoxide polymers were investigated. Threefold or more increases in char yield (up to 60%) were obtained on the nitrated analogs. Correspondingly lower maximum rates of weight loss were observed. In one case, this was lowered by 700%. These effects were enhanced when highly functional and highly aromatic epoxide resins were used. The sample size and heating rate employed had pronounced effects upon the amount of char formed during thermal degradation. Analysis of char residues indicates hetero-ring formation for the nitrosubstituted systems during pyrolysis. (Author)
