Abstract
ABSTRACT The impact of thermo-oxidation on the permeation process in a series of BIIR or bromobutyl compounds has been investigated. Methyl salicylate (MS) was used as the simulating chemical agent, and the permeation rate was measured gravimetrically using vapometers. Heat aged samples at 120 °C increased in stiffness with an accompanying decline in ultimate properties and network chain density. A reduction in permeability was found, driven primarily by the reduced solubility of MS in the thermo-oxidized BIIR matrix. The formation of a secondary oxidized chain network has been proposed to explain the decline in MS solubility. The loss of plasticizer during the heat aging process is responsible for the reduction of the MS diffusibility. Diffusion-limited oxidation during thermo-oxidation is also a likely factor in affecting the MS transport process.

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
