摘要：

Thermal decomposition of poly-5-vinyltetrazole has been investigated by the methods of chemical and complex thermal analyses under isothermal and nonisothermal conditions, infrared spectroscopy and gas chromatography. Activation parameters of the decomposition process have been evaluated by various methods. The analysis of the obtained data leads to the conclusion that, depending on the conditions of the experiment, decomposition of polymer tetrazole cycles may proceed in two parallel ways: either destruction of the tetrazole rings with elimination of hydrogen azide, or their tautomeric isomerization into the respective azidoazomethine, from which a nitrogen molecule is then 'chipped off'. © 1990.
