Abstract

fetched live from OpenAlex

Abstract The effects of reactive compatibilization and extruder rotation rate on morphology development of polymer blends are studied. Morphology develops faster in compatibilized blends than that in their uncompatibilized counterparts. Based on force analysis, it has been proved that compatibilization facilitates dispersion by reducing slip at the interface of polymer phases. Rotation rate influences the morphology development of polymer blends by changing the residence time of polymers in the extruder. For uncompatibilized blends, the 400 rpm run results in finer microstructure at the outlet of the extruder than the 1 000 rpm run. Compatibilization suppresses this effect by reaching a steady‐state morphology before the outlet and results in similar microstructure for the 400 and 1 000 rpm runs. magnified image

Teacher imitation

Not 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.
