Abstract
Abstract The kinetics of the copolymerization of alpha‐methyl styrene (AMS) and butyl acrylate (BA) have been revised to include both the bulk and solution systems. Reactivity ratios and other kinetic parameter estimates based upon a copolymerization model developed by Kruger have been ascertained for a range of temperatures (60–140°C) and at a single solvent level (23 wt%). Full conversion range studies have been completed at two different solvent levels to determine the effects of feed composition, solvent, and chain transfer agent (CTA) on the rate of polymerization, copolymer composition, and the resulting molecular weight.

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
