1 Fig. 2 Dissolution mechanism of nylons in the TFA:acetone mixture.
Dissolution mechanism of nylons in the TFA:acetone mixture. (A) Boiling point (B. P.) and (B) vapor pressure (V. P.) of the solvent mixture of TFA:acetone as a function of acetone mole fraction (Xacetone). The inset shows the schematic of the interactions between TFA and acetone molecules for 50:50 mol % TFA:acetone. (C) 1H shift of the NMR (850.3 MHz at 298 K) spectra for different solvent mixtures of TFA:acetone-d6 as a function of acetone mole fraction. (D) 1H shift of the NMR (850.3 MHz at 298 K) spectra of nylon-11 solution for different solvent mixtures of TFA:acetone-d6 as a function of acetone mole fraction. The solubility region for nylons is marked in green. The insolubility region due to the shielding of the proton is marked in red. The inset shows the schematic of the shielding of TFA by acetone molecules for 75:25 mol % TFA:acetone. Saleem Anwar et al.
