Abstract
Reported are the preparation and application of a triblock terpolymer poly(ethylene oxide)- ONB -poly[2-(perfluorooctyl)ethyl methacrylate]- block -poly(2-cinnamoyloxyethyl methacrylate) (PEO- ONB -PFOEMA- b -PCEMA). Here PEO is water-soluble, PCEMA is photo-cross-linkable, PFOEMA is of low surface tension, and ONB denotes a photocleavable o -nitrobenzyl unit at the junction of the PEO and PFOEMA blocks. To prepare the copolymer, a macroinitiator bearing an ONB unit between PEO and the initiating site was first synthesized. FOEMA and 2-trimethylsilyloxyethyl methacrylate (HEMA-TMS) were then sequentially polymerized by atom transfer radical polymerization (ATRP) to yield the triblock copolymer PEO- ONB -PFOEMA- b -P(HEMA-TMS). Removal of the trimethylsilyl groups from the P(HEMA-TMS) block and cinnamation of the resultant poly(2-hydroxyethyl methacrylate) block with cinnamoyl chloride resulted in the targeted triblock copolymer. PEO- ONB -PFOEMA- b -PCEMA formed micelles in tetrahydrofuran/water at the water volume fraction of 80%, in which only the PEO block was soluble. Upon photolysis, the micellar PCEMA cores were cross-linked and the micellar coronal PEO chains were cleft, resulting in the precipitation of cross-linked PFOEMA- b -PCEMA nanoparticles. Films of the nanoparticles were water- and oil-repellent due to the exposure of the initially hidden PFOEMA block.

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
