Thermal Decomposition of Photocurable Energetic APNIMMO Polymer.

Photocurable energetic polymer contains energetic groups (explosophores) and provides fast curable property for 3D printed propellants. Acrylate‐terminated poly‐3‐nitratomethyl‐3‐methyloxetane (APNIMMO) was prepared for the stereolithography (SLA) printing. This work outlines the thermal decomposition process of APNIMMO. The thermal behaviour and decomposition kinetics were investigated by means of the non‐isothermal DSC (differential scanning calorimetry) techniques. The Arrhenius parameters were studied by different isoconversional Kissinger method. Additionally, simultaneous TG‐DSC‐FTIR‐MS were employed to corroborate the thermal analysis results. The obtained results from the different techniques are presented and discussed. [ABSTRACT FROM AUTHOR]
