TL;DR: In this article, a synthesis of NCA's of α-amino acids using bis(trichloromethyl) carbonate has been reported; the triphosgene is used to supply phosgenes in situ in stoichiometric amounts; it is particularly effective for preparing NCA of amino acids with long, aliphatic side chains.

TL;DR: In this article, the gas permeability, diffusivity, and solubility of polysulfone bearing basic aryl substituents were determined at 35 °C and pressures up to 20 atm.

TL;DR: 17 derivatives of chitosan consisting of a variety of N-aryl substituents bearing either electron-donating or electron-withdrawing groups are synthesized and it is found that derivatives with higher ES exhibited reduced antibacterial activity due to low quaternary ammonium moiety content.

TL;DR: Evidence is provided for the miscibility between chitosan and cellulose in the solid state using 1-butyl-3-methylimidazolium acetate as solvent media and for the increased Ea for thermal decomposition for all the polymeric blends.

TL;DR: In this article, N,N,N-dimethylaminobenzyl and N-pyridylmethyl substituents with iodomethane under basic conditions led to quaternized chitosan and quaternised N-dimethylation.
