Abstract
We report the use of atom transfer radical polymerization (ATRP) to graft off polymeric microspheres. Residual vinyl groups on nonswellable poly(divinylbenzene-80) microspheres were converted into ATRP initiators by hydroboration/oxidation followed by esterification. Subsequent grafting by ATRP of poly(hydroxylethyl methacrylate) (poly(HEMA)) and poly((dimethylamino)ethyl methacrylate) (poly(DMAEMA)) led to hydrophilically modified microspheres. The surface properties of these microspheres, FT-IR spectra, and potentiometric titration confirm the successful modification. In addition, swellable, lightly cross-linked poly(DVB- co -HEMA) microspheres were modified in a similar manner by grafting, i.e., methyl methacrylate (MMA) and glycidyl methacrylate (GMA), to form graft block copolymers including poly(MMA- b -DMAEMA), poly(MMA- b -trimethylammonium ethylmethacrylate (TMAEMA)), and poly(MMA- b -GMA). Microphase separation of the grafted amphiphilic block copolymers was studied by scanning electron microscopy. The microspheres modified with poly(MMA- b -DMAEMA) and poly(MMA- b -TMAEMA) show polyelectrolyte properties.

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
