Abstract
Abstract Decomposition mechanisms of propellants are of great interest in understanding performance issues of chemical propulsion systems. The characterization of physico‐chemical properties of glycidyl azide polymer (GAP), specifically deuterated analogs, was investigated in this study. The purpose of this new approach is to identify the key steps in thermal decomposition mechanism of GAP. The present work shows that the use of deuterated GAP is a good method to study the decomposition pathway of energetic polymers. The polymerization process was successful, but was nevertheless affected by the use of the isotopic monomer since the resulting polymers had a slightly lower molecular weight. The chemical characterization of the deuterated GAPs by NMR and FTIR confirm the structure of these new polymers. The TGA analyses show a larger weight loss during the first step of decomposition for labeled GAP suggesting that molecular nitrogen and heavier compounds are produced simultaneously.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
