Abstract
Abstract Olefin block copolymers (OBCs) are thermoplastic elastomers with unique statistical multiblock structures produced by chain‐shuttling polymerization. In this study, a dynamic Monte Carlo model is used to simulate the effect of changing chain‐shuttling ( k CS ), catalyst deactivation ( k d ), and chain transfer ( k tr ) rate constants on the microstructure of OBCs made in a semi‐batch reactor. The simulations show how each rate constant governs different aspects of the OBC chains and provide guidelines on how to fine‐tune OBC microstructure to achieve precisely designed multiblock structures.

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
