Abstract

fetched live from OpenAlex

Abstract Triazole cross‐linked energetic polymer networks obtained from the reaction of dialkyne curing agents with glycidyl azide polymers (GAP) or poly(2,2‐[bisazidomethyl]propane‐1,3‐diyl carbonate) (poly[BAMPC]) were studied, and their thermal and mechanical properties are reported. The dialkynes studied include bis(propargyl)ether (BPE), bis(propargyl)malonate (BPM), and 4,4’‐diacyanohepta‐1,6‐diyne (DCHD), three compounds previously described as curing agents for glycidyl azide pre‐polymers. The cured polymer networks display a wide range of properties dependent on the nature of the azido pre‐polymer, the nature of the dialkyne, the alkyne/azide molar ratio, and the molecular weight of the pre‐polymer used. Results confirm that the three dialkynes are effective curing agents able to form rigid networks out of either pre‐polymer and that the lighter molecular weight BPE and DCHD both improve mechanical properties of cured networks with less dilution of the system's energetic content. Triazole cross‐linked poly(BAMPC) networks were studied for the first time, and promising physical and mechanical properties are reported.

Teacher imitation

Not 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.
