Synthesis and Characterization of Tunable Dual‐pH Switchable Zwitterionic Copolymers
Bibliographic record
Abstract
A dual‐pH switchable zwitterionic copolymer, poly(2‐(dimethylamino)ethyl methacrylate‐co‐acrylamide‐co‐acrylic acid) (poly(DMAEMA‐co‐AM‐co‐AA)), is synthesized by random copolymerization. Characterized by a sharp change in solution turbidity, the conformation of such polymers in aqueous solutions can be switched at both acidic (low pH) and alkaline (high pH) conditions, with the switching pH being finely tunable by controlling the molar ratio of cationic and anionic functional groups of the copolymer. Study with quartz crystal microbalance with dissipation confirm the origin of the conformational change from electrostatic attractions between cationic DMAEMA and anionic AA functional groups. image

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.
