Synthesis of Arborescent Copolymers by a One‐Pot Method
Bibliographic record
Abstract
Abstract A “grafting from” scheme was developed for the preparation of arborescent copolymers in one single reactor, by anionic copolymerization of styrene with 1,3‐diisopropenylbenzene and activation of the pendent isopropenyl moieties with sec ‐butyllithium. Arborescent polystyrene‐ graft ‐poly( tert ‐butyl methacrylate) copolymers were thus obtained by addition of tert ‐butyl methacrylate to linear and G0 macroinitiators, respectively. Arborescent polystyrene‐ graft ‐[polystyrene‐ block ‐poly(2‐vinylpyridine)] copolymers were also synthesized by successive additions of styrene and 2‐vinylpyridine to the same macroinitiators. The copolymers were characterized by SEC‐MALLS and 1 H NMR analysis. magnified image

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; a candidate call from one teacher head, not a consensus.
