New Materials Using Atom Transfer Radical Polymerization: Microcapsules Containing Polar Core Oil
Bibliographic record
Abstract
A technique for encapsulation of polar organic solvents using Atom Transfer Radical Polymerization (ATRP) by suspension polymerization is presented. ATRP was used to synthesize crosslinked amphiphilic copolymers based on oil soluble and water soluble comonomers by suspension polymerization. We demonstrate that the slow rate of ATRP crosslinking reactions allows enough time for polymer to migrate in the oil droplets from the interior to the oil-water interface, yielding the thermodynamically favored capsular morphology. This finding is relevant for the encapsulation of polar core oils where the driving force for polymer migration to the oil-water interface is weak. Using less polar xylene as core oil we have shown that polymer architecture can strongly influence its solubility in the oil phase and therefore the morphology of the suspension polymer particles.

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.
