P(AN-VAc-PMMT) nanocomposites were prepared usingin situemulsion polymerization and further confirmed by FTIR. A polymerizable quaternary ammonium ion monomer was used to modify montmorillonite. XRD testing showed that the quaternary ammonium ion was successfully intercalated into the montmorillonite chip layer. This is the first paper to discuss an investigation of P(AN-VAc-PMMT) nanofiber morphology using SEM. The fibers were prepared through electrospinning.

Nowadays, the development of new approaches which smartly bypass the use of harsh reaction conditions and hazardous chemicals covers a pivotal role. In this research paper the synthesis, characterization and application of novel libraries of triazine bis-quaternary ammonium salts, employed as coupling agents to produce amides, is reported. Full characterization of the novel compounds by 1H and 13C NMR, FT-IR spectroscopy, ESI-HRMS and elemental analysis (EA) is provided. Furthermore, a comparison in terms of activity of the preformed triazine compounds versus in situ formulations has been evaluated for the formation of amides in the presence of phenylethylamine and different aliphatic or aromatic acids. A possible correlation between the chemical structure of the triazine and their reactivity for the formation of the triazine bis-quaternary ammonium salts is also reported. Moreover, best performing condensation agents have been further tested for the cross-linking of collagen powder as possible wet white tanning systems, for sustainable and environmentally friendly leather tanning.
