Abstract

With using DSC, TG, IR spectroscopy, X-ray phase analysis and chemical methods of analysis, an active role of hydrogen chloride, which is a part of the dihydrate 2.4-diamine-6-methyl-1.3.5-triazine hydrochloride C4H7N5∙HCl∙2H2O, in improving the conditions for the condensation of the triazine fragment has been established. This is explained by the intramolecular interaction of acid with ammonia released at the time of condensation of С4Н7N5 with the formation of ammonium hydrochloride, which is found in decomposition products. As a result, the triazine sublimation that accompanies the polymerization process is suppressed. The detection of guanidine hydrochloride in the products of thermolysis along with ammonium chloride and the absence of a methyl group in C-N-H-containing graphite-like materials indicates a complex mechanism of decomposition of the triazine fragment.
