Abstract
Poly(2‐(diethylamino)ethyl methacrylate) (PDEAEMA) macroinitiator is prepared in water by aqueous reversible addition–fragmentation chain transfer (RAFT) polymerization under CO 2 atmosphere, and then used directly as a stabilizer in emulsion polymerization, without requiring further purification, to yield CO 2 ‐switchable latexes of poly(methyl methacrylate) (PMMA) and polystyrene (PS). Chain extension of the PDEAEMA macroinitiator with styrene (S) leads to the in situ formation of poly(DEAEMA‐ b ‐S) diblock copolymers in a one‐pot process. The final latexes are pH and CO 2 ‐responsive and can be coagulated by N 2 bubbling and subsequently redispersed by CO 2 bubbling. The effects of various parameters on the latex properties are investigated, including pH, concentration of macro‐RAFT agent, using MMA as comonomer and initiator concentration. The results show that replacing only 5 mol% MMA in emulsion polymerization of styrene eliminates the induction time and also has a significant influence on the particle size distribution. 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 it
