Synthesis and thermal degradation of phosphazene containing the epoxy group
Bibliographic record
Abstract
Nous avons synthetise une resine epoxyde par condensation de l'hexachlorocyclotriphosphazene avec le 2,3-epoxy-1-propanol en presence de triethylamine, pour obtenir le Hexaglycidylester Cyclotriphosphazene (HGCP). Sa structure a ete confirmee au moyen de spectroscopie IR-TF et RMN 1 H, 13 C, 31 P. La resine epoxyde obtenue est ensuite reticulee thermiquement, avec la methylene dianiline (MDA). La stabilite thermique de cette resine thermodurcie avec la methylene dianiline (MDA) a ete etudiee par l'analyse thermogravimetrique (ATG), et comparee a celle du diglycidylether du bisphenol A (DGEBA). Les gaz degages pendant l'analyse ATG en atmosphere air ont ete etudies au moyen de la thermogravimetrie couplee a la spectroscopie infrarouge a transformee de Fourier (TG-FTIR), alors que les residus solides ete analyses par FTIR. La resine thermodurcie a montre une meilleure stabilite thermique a temperature elevee avec de plus grands rendements de residus charbonneux a 500°C par rapport a la resine conventionnelle DGEBA.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
