Abstract
Free radical polymerization of alkyl monomers using water soluble initiator was impractical due to phase separation, it can be overcome byintroduction of phase transfer catalyst (PTC). Polymerization using this technique results in polymers of high molecular weight and goodmechanical properties. The catalytic activity seems to increase by the aromatic substitution in the alkyl chain of PTC. In the present study kinetics ofpolymerization of methyl methacrylate in ethyl acetate/water biphasic media using potassium peroxomonosulfate (PMS) as water soluble initiatorand aromatic substituted PTC was investigated. The order of the reaction was found to be unity with respect to monomer concentration and 0.5-1.0for PMS and catalyst concentration. The poly methyl methacrylate formed shows high molecular weight measured from the viscosity. The productformed was endorsed by IR, thermal analysis and the crystallinity was studied from X-ray diffraction.

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
