Abstract
Lignin grafted acrylic acid-acrylamide superabsorbent resin LS-g-P(AA-co-AM) was prepared by solution polymerization with temperature step-increasing mode.FTIR,SEM and TGA were employed to characterize the superabsorbent resin.Water absorbency and physiological saline absorbency of the resin were measured.LS-g-P(AA-co-AM) shows high water absorbency(1 156 g/g) and high physiological saline absorbency(122 g/g).FTIR analysis confirmed the graft copolymerization of lignosulfonate with acrylic acid and acrylamide.SEM photograph show the lignin-based superabsorbent resin had formed porous sponge structure,and thermogravimetric analysis indicat the superabsorbent resin had good thermal stability.Introduction of lignosulfonate to the superabsorbent resin has improved the resin's salt resistance,and the development of this kind of lignin-based superabsorbent resin provides a new approach for the utilization of lignin.

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
