Abstract
The paper presents a non-isothermal kinetic study of the degradation process of some aromatic copolyethers containing a tetra-methylenic spacer. The polymers were synthesized using the phase transfer catalysis technique, starting from 1,4-dichlorobutane and various bisphenols (4,4 ' -dihidroxyazobenzene, 4,4 ' -dihydroxydiphenyl, bisphenol A and 2,7-dihydroxynaphthlene). Dynamic thermal analysis methods such as ATG, DTG and ATD were used. In order to work out the basic kinetic parameters and the reliance between activation energy and conversion degree, differential methods based on the `order reaction model' were applied and standard kinetic models were also used. The thermostability of the good samples up to 320 ° C was demonstrated. The degradation mechanism took place by successive reactions, controlled by a nucleation process influenced by the polymer molecular structure.

Full frame distilled prediction
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
