Abstract

fetched live from OpenAlex

Abstract The use of a tubular reactor for conducting living radical polymerizations by atom transfer radical polymerization (ATRP) was investigated. Solution polymerization experiments were performed with styrene and butyl acrylate to elucidate the influence of a continuous reaction process on conversion, molecular weight, and polydispersity compared to batch polymerization experiments. The continuous polymerizations were well controlled. Initial conversion was found to be slightly higher in the tubular reactor than in a batch polymerization run at similar conditions, while number average molecular weight and polydispersity are comparable between the continuous and batch processes. Residence time distribution studies showed the reactor exhibits nearly plug flow behavior. magnified image

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.
