摘要: Abstract The thermal decomposition of poly-1-vinyltetrazole (PVT) has been studied by thermogravimetry in isothermal conditions and DSC volumetric analysis non-isothermal conditions. gaseous condensed products thermolysis were identified. It shown that nitrogen is the single product PVT. Cyanamide carbodiimide fragments fixed on polymer carbochain which are able to cyclotrimerize into triazines isotriazines respectively identified phase. kinetic curves have a sufficiently long induction period fit an equation autocatalysis first order. limiting stage PVT opening tetrazole rings. activation energy this process calculated 148 kJ moP'; it 140 mol−1.
