Energetic Nitrogen‐Rich Polymers with a Tetrazene‐Based Backbone

Abstract : New energetic polymers were synthesized from monomers featuring the trans-2-tetrazene unit. In contrast to traditional binders, such as the inert hydroxytelechelic polybutadiene or the glycidyl azide polymers-where the energetic features are on the side chains-, the energetic groups in the polytetrazenes are incorporated directly in the polymer backbone. Thermal analyses evidenced that decomposition occurs at ~130 °C, regardless of the polymer structure. Glass transition temperatures range from-34.2 to 0.2°C, and they could be lowered further (to-61°C) with the help of a new diazido tetrazene energetic plasticizer. Interestingly, hexafluoro isopropanol (HFIP) enables a complete, room temperature depolymerization within one week. This should enable the recycling of the unused pyrotechnic compositions based on these new binders.
