Abstract

The dissolution process for the two-component system such as nylon-4,6 (PA4,6) and water was investigated using wide-angle X-ray diffraction and Fourier transform infrared (FTIR). It was observed that the superheated water as a solvent facilitates the growth of single crystals and to form water intercalated highly crystalline single crystals. It was found that the bound water molecules exit from the lattice around the Brill transition temperature of PA4,6 upon the release of vapor pressure. It was also found that at 200 °C the water vapor pressure was 1.25 MPa and therefore complete dissolution was achieved even at moderate pressures.
