Abstract
A comprehensive simulation of the diimide hydrogenation process is carried out by taking into account the diimide generation reaction, the hydrogenation reaction, the side reaction between hydrogen peroxide and diimide, the disproportionation of diimide, and the diimide diffusion process. The relative magnitude of these rate constants with the diffusivity of diimide is estimated. It is found that the diimide diffusion interferes with the diimide hydrogenation of the latex of nitrile butadiene rubber (NBR), even though the particle diameter is as small as 72 nm. The interference of diimide diffusion makes it very difficult to achieve above 90% of hydrogenation without significant gel formation. Using core−shell latex with an NBR shell may help to solve the low hydrogenation efficiency and the gel formation at the same time.

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
