Bibliographic record
Abstract
Abstract Here we describe a facile approach to preparing cationic bottlebrush brush polymers via sequential surface‐initiated (SI) ring‐opening metathesis polymerization and SI activators regenerated by electron transfer atom transfer radical polymerization. These techniques afforded both bottlebrush polymer brushes and their linear polymer brush analogues with cationic triphenylphosphonium pendant groups. Utilization of two controlled polymerization techniques with orthogonal requirements for monomers and additives allowed the polymerization of the backbone and the pendant side chains to be controlled independently. Grafting polymer side chains to a polymer brush backbone resulted in a thickness increase of ca 70%, indicating that the polymers are forced into a stretched conformation with greater surface coverage than was afforded by the linear brush polymers. As a result of the stretched conformation, greater ionic conductivity in the bottlebrush brush architectures was observed. © 2022 Society of Industrial Chemistry.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
