The Preparation of New Polystyrenic Onium and Substituted Poly(Thionylphosphazene) Antimicrobials
Bibliographic record
Abstract
With increasing concern over AMR in bacteria, the synthesis of traditional and non-traditional antimicrobial polymers is of interest. The first project focuses on preparing new polystyrenic quaternary compounds that will be grafted to plastic surfaces. Three quaternary styrenic polymers (4-6) and their respective random copolymers with styrene (7-9) were synthesized and grafted onto HDPE, where biological testing of coatings 4, 5 and 7 using the LDI protocol showed some bacterial reduction with alkyl chain lengths ≥ 4. The second project focuses on synthesizing novel thionylphosphazene monomers and looking into greener polymerization routes. Two novel thionylphosphazene monomers (13-14) were synthesized and a greener polymerization route was obtained using Lewis acid-catalyzed microwave irradiation. The third project involves undertaking DFT calculations of various cyclic thionylphosphazenes to study alternate polymerization routes of these compounds. Energy calculations showed the potential for substituted thionylphosphazenes with small substituents to polymerize under ambient temperatures with Lewis acid catalysts.

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.
