Abstract

fetched live from OpenAlex

Abstract We used neutron reflectivity to measure the interfacial width in the immiscible system polystyrene/poly( n ‐butyl methacrylate) (PS/P n BMA). Measurements were made on the same samples at temperatures ranging from below the glass‐transition temperature ( T g ) of PS to slightly above. We observed significant broadening of the interface at temperatures below the T g of PS, indicating chain mobility below the bulk T g value. The interfacial width exhibited a plateau at a value of 20 Å in the temperature range of 365 K < T < 377 K. A control experiment involving hydrogenated and deuterated PS films (hPS/dPS) showed no such broadening over the same temperature region. The results are consistent with a reduction of the T g of PS in the interfacial region of ∼20 K. © 2001 John Wiley & Sons, Inc. J Polym Sci Part B: Polym Phys 39: 2664–2670, 2001

Full frame distilled prediction

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.
