Viscoelasticity, Leachability, and Antimicrobial Activity of Poly(vinyl chloride) Blended with Benzyldimethyltetradecylammonium Bis(2-ethylhexyl) Sulfonatosuccinate
Bibliographic record
Abstract
Abstract Benzyldimethyltetradecylammonium (BA14+) salt with bis(2-ethylhexyl) sulfonatosuccinate (BEHS−) anion maintains its liquid state even at room temperature, so it can be regarded as a halogen-free low-volatile liquid material. In this study, the potential use of BA14BEHS as additive for poly(vinyl chloride) (PVC) has been investigated. The temperature dependence of the storage and loss moduli of PVC films blended with BA14BEHS showed a similar trend of that with a traditional plasticizer bis(2-ethylhexyl) phthalate. The glass transition temperature of the PVC films determined as the peak top temperature in loss modulus was lowered with increasing BA14BEHS content. The 10% BA14BEHS-blended PVC film was placed in contact with water and heptane, but BA14BEHS could not be detected from the aqueous and organic media. The results indicate that BA14BEHS can be applied as a plasticizer for PVC. Since BA14BEHS can be used to give textiles antimicrobial properties, the activity of the BA14BEHS-blended PVC film was assayed against Escherichia coli JM109. In spite of the low-leachability of BA14BEHS, the PVC film showed a significant antimicrobial activity.

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.
