Abstract
The polymerization of 2,3,5,6-tetraphenylhydroquinone (or 2,2‘,3,3‘,5,5‘-hexaphenyl-4,4‘-dihydroxybiphenyl) with α,ω-tetrahydroperfluoroalkanediol and decafluorobiphenyl was carried out to synthesize a series of copolymers III ( M w = 49 100−80 900). The copolymers III are composed of arylene ether (10−30 mol %) and fluorinated alkane (90−70 mol %) moieties. The reaction of III with chlorosulfonic acid gave sulfonated polymers IV, which are soluble in polar organic solvents and form flexible and transparent films by casting from solution. The polymers IV have glass transition temperatures of 109−155 °C and decomposition temperatures of ca. 300 °C. The hydrated polymers show protonic conductivity (3.4 × 10 -3 S cm -1 ), which does not decrease at temperatures up to 170 °C.

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
