Amphiphilic hyperbranched polymers from the copolymerization of a vinyl and divinyl monomer: The potential of catalytic chain transfer polymerization
Bibliographic record
Abstract
This feature article focuses on the synthesis of amphiphilic hyperbranched polymers. There is a growing interest in the properties of these nanostructured materials and the copolymerization of a vinyl and divinyl monomer in the presence of a chain transfer agent, provides a simple, versatile and scalable synthesis route. In particular the use of catalytic chain transfer (CCT) will be highlighted. CCT is a very efficient and versatile chemistry for molecular weight control and the synthesis of vinyl ω-end functionalized polymers (e.g. macromonomers) in free radical polymerization. This makes CCT an interesting option for the synthesis of hyperbranched polymers as the use of cobaloxime complexes allows for control over the polymer architecture as well as ω-endgroup functionality. An overview of the synthesis of hyperbranched polymers via the copolymerization of a vinyl and divinyl monomer is presented, followed with a number of examples of amphiphilic hyperbranched polymers and their applications.

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.
