Abstract
A novel process is described for making integral multilayered polymers with the layers separated by discontinuous narrow gaps containing air and/or a blowing agent. The two step process involves first introducing a low degree of entanglement among some of the polymer chains and then breaking apart these entanglements using a blowing agent to give the discontinuous gaps that resemble elongated, narrow cells. The layer density can be controlled within a wide range, typically 10 to 2000 layers/mm, while the gap between the layers is < 100 nanometers. These layered materials, called nanolayered polymers or layered foams, are mechanically strong and have excellent thermal and electrical, and, possibly, sound insulation properties. The nanolayering process is complimentary to the process described recently (Handa and Zhang, Cellular Polymers 19, (2000) 1) to make microlayered polymers.

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 it
