Abstract

fetched live from OpenAlex

Rheological experiments in shear and uniaxial elongational flows have been carried out on a model immiscible blend made of PS and PMMA with various compositions. Experimental results showed a negative deviation behavior from the log-­additivity rule both in shear and elongation for blends having PS as the continuous phase. Such behavior can be attributed to the interfacial slip that results from a lack of entanglements and thus from the weak adhesion at the interface, as verified by Scanning Electron Microscopy observations. The obtained reduction in viscosity was compared to the predictions of Bousmina-­Palierne-­Utracki (1999) and Adhekari-­Goveas (2004) models. Addition of 1wt% of a block copolymer resulted in a partial suppression of the interfacial slip.

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.
