Abstract
This paper investigates the effect of the incorporation of organosolv lignin and a chain extender on the compatibility between polylactide and poly(butylene adipate‐co‐terephthalate). Bioblends were processed using melt extrusion and injection molding techniques. A reaction was observed during the melt processing as the force increased as the amount of ADR in the formulation increased. This reaction was investigated by Fourier transform infrared spectroscopy. The morphological images showed a good dispersion and an absence of phase separation by the inclusion of the chain extender. The incorporation of the chain extender enhanced the tensile properties and modulus characterization of the bioblends. Dynamic mechanical analysis and rheological characterization revealed that the addition of chain extender increased the storage modulus of the bioblends. Differential scanning calorimetry analysis showed a good miscibility between PLA and PBAT in the presence of OL and the chain extender, while thermogravimetric analysis showed enhancement in the thermal stability by inclusion of the chain extender.

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
