Effect of Copolymer Addition on Drop Deformation during Uniaxial Elongation and during Relaxation after Cessation of Flow
Bibliographic record
Abstract
The effect of diblock copolymer addition on the rheological behavior and on the morphology of a PS/PMMA blend during elongation and after cessation of flow is discussed. The blends' morphology was characterized during deformation and at different stages of the relaxation process. Throughout all experiments, the copolymer concentration was selected to fall either below or above the critical concentration of interface saturation. The results show an unexpected fast relaxation at low copolymer concentration, while a much slower stress relaxation is observed at higher concentrations. Such effects were attributed to the competition between hydrodynamic convection of the copolymer molecules and the Marangoni stresses. The local entanglements of the copolymer chains were found to play a major role in such competing effects.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
