Polymerizable anthracene derivatives for labeling emulsion copolymers
Bibliographic record
Abstract
Abstract We describe the synthesis of three anthracene–methacrylate monomers [9‐methacryloxymethyl‐10‐methyl anthracene ( 4 ), 9‐methacryloxyethyloxymethyl‐10‐methyl anthracene ( 5 ), and 9‐methacryloxy‐10‐methyl anthracene ( 6 )] as well as their emulsion copolymers containing butylacrylate. When films prepared from latex dispersions containing 4 or 5 were heated, the anthracene (An) group was cleaved from the polymer at temperatures above 120 °C. Lower temperatures induced this reaction when strong acids were present. In 4 and 5 , the polymerizable group is connected to the An ring via a 9‐CH 2 O linkage. The cleavage reaction requires more stringent conditions when the connection involves a benzylic ether ( 5 ) instead of a benzylic ester. Polymers prepared from 6 , with an AnO bond, were stable for 1 h at 150 °C in the presence of 0.5 wt % p ‐toluene sulfonic acid. © 2001 John Wiley & Sons, Inc.

How this classification was reachedexpand
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.
