Influence of the Reference Temperature on the Orientation and Relaxation of Miscible Polystyrene/Poly(vinyl methyl ether) Blends
Bibliographic record
Abstract
The deformation and relaxation behavior of polymers depends heavily on temperature. In miscible polystyrene/poly(vinyl methyl ether) (PS/PVME) blends, which possess a broad glass transition region, polarization modulation infrared linear dichroism (PM-IRLD) measurements show that when the mean glass transition temperature ( T g ) is used as the reference temperature, the orientation and relaxation of orientation of PS in the blends depend significantly on the composition. In contrast, similar values are obtained for blends containing between 40 and 100% PS when the end of the glass transition region ( T g f ) is used as the reference temperature. Physical aging experiments made by differential scanning calorimetry indicate that T g f can be associated with the highest temperature at which enthalpic relaxation occurs, above the mean T g of the blend. Both series of results have been analyzed, first, by considering the presence of concentration fluctuations in the miscible blends and, second, in the framework of the Lodge−McLeish model.

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.
