Abstract
Abstract Summary: Methacrylate copolymers produced under higher temperature starved‐feed conditions are affected by depropagation, and some binary systems also experience a penultimate effect. In this work a generalized set of equations has been developed to describe the combined effect of depropagation and penultimate copolymerization kinetics on instantaneous copolymer composition and average copolymerization rate coefficients. Limiting cases applicable to the methacrylate/styrene system are examined. When combined with depropagation, penultimate kinetics not only decrease the effective propagation rate coefficient but also deviate from terminal model predictions of polymer composition. Copolymerization chain growth with penultimate kinetics and depropagation. magnified image Copolymerization chain growth with penultimate kinetics and depropagation.

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
