Abstract
Abstract Control of the reactivity of natural polymers – such as semicrystalline cellulose – through polymorphic transitions is a potent, yet underexplored tool in modern polymer science. Here, the degradation behavior of three artificial cellulose polymorphs (cellulose II, III I , and III II ) in the presence of hydrogen chloride vapor is explored. While the ultimate results of hydrolyses correspond to those found for aqueous HCl, the kinetic scission models exhibit a unique trend for each polymorph, unlike those reported for aqueous acid or enzymatic hydrolyses. In addition to the polymorphic distinctions, these atypical trends are attributed to the nonequilibrium in the hydrolysis set up and the irregular adsorption of HCl molecules to the substrate surfaces. The results point to a new way of approaching the reactivity of natural polymers where polymorphism is regarded as one of the parameters for the kinetics and outcome of chemical reactions.

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
