Nitrogen‐Rich Polymers Based on 5‐Bromo‐1‐vinyl‐1H‐tetrazole

Nitrogen‐rich polymers with contents of nitrogen between 50 and 60 % were synthesized by radical polymerization using 1‐(1‐vinyl‐1H‐tetrazol‐5‐yl)hydrazine and 1‐methyl‐1‐(1‐vinyl‐1H‐tetrazol‐5‐yl)hydrazine. The monomers were obtained by substitution reactions of hydrazine derivatives and 5‐bromo‐1‐vinyl‐1H‐tetrazole. Moreover, the poly‐1‐(1‐vinyl‐1H‐tetrazol‐5‐yl)hydrazine was converted into the corresponding 5‐azidotetrazolyl‐containing polymer by the reaction with sodium nitrite. The polymers were characterized by measurements of the molecular weights, by vibrational spectroscopy (IR) and elemental analysis. The thermal stability was determined by differential scanning calorimetry and the sensitivity towards friction and impact were determined by BAM standards. The energetic properties were investigated by bomb calorimetric measurements and calculations with the EXPLO5 software. The high stability of the polymers towards impact and friction, along with their sufficient thermal stability (175–279 °C) and moderate energetic characters renders these polymers into promising compounds for an application as environmently friendly nitrogen‐rich polymers.
