Copolymerization of Hydrophilic and Hydrophobic Monomers in Water Assisted by Cyclodextrins
Bibliographic record
Abstract
ABSTRACT To facilitate the copolymerization of both hydrophobic and hydrophilic monomers in aqueous media, cyclodextrins (CDs) are introduced to form inclusion complexes with the hydrophobic monomers. As a proof of concept, β‐CD is used to solubilize a hydrophobic acrylamide derivative of cholic acid (CAAM) in water, enabling its copolymerization with acrylamide to occur in a common and benign solvent, that is, water. An excess of β‐CD is needed to effectively solubilize the cholic acid monomer CAAM in water, leading to the synthesis of a thermoresponsive polymer. The CAAM content in the final copolymer is ca. 2.5 mol%, in contrast to the 5 mol% contained in the feed. Notably, this investigation underscores the usefulness of inclusion complexation in the copolymerization process. The same monomer formed a looser inclusion complex with γ‐CD, which has a larger cavity than β‐CD, and produced a copolymer with only 0.74 mol% of CAAM, indicating the importance of the stability of complexation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
