Abstract
Anionic polyelectrolytes bearing phosphate or phosphonate groups were compared to poly(acrylic acid- co -acrylamide) as reinforcing polymers for paper filled with calcium carbonate. Cationic polyvinylamine, PVAm, was used to promote adsorption of the anionic polymers onto fiber and filler surfaces in the aqueous papermaking suspension. Both poly(acrylamide- co -vinyl phosphonate), PAMVP, and phosphate esters of poly(vinyl alcohol), PVAP, gave stronger paper than did the acrylate copolymers. PAMVP bound soluble calcium ions, resulting in the formation of multichain colloidal-sized clusters. Subsequent addition of PVAm produced dispersed, cationic polyelectrolyte complexes. The polyacrylates bound less soluble calcium and formed weakly scattering clusters. It is proposed that the phosphate and phosphonate groups promote polymer adhesion to the calcium carbonate surfaces, resulting in stronger paper.

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
