Abstract

fetched live from OpenAlex

Stable emulsions of polystyrene have been prepared by nitroxide-mediated living-radical miniemulsion polymerization. Optimization of the ratios and amounts of surfactant, cosurfactant, and nitroxide provided both good latex properties and good living-radical chemistry. Results were superior to those obtained in comparable bulk polymerizations. Conversions of 87% were obtained in 6 hours at 135°C without the use of a rate accelerant and the molecular weight distributions were typically in the 1.1 range.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
