Abstract

The relationship between the logarithmic hydraulic permeability and the reciprocal absolute temperature for a novel hydrophilic polyamide membrane peculiarly refracted at about 27°C, which was inferred to be some kind of transition point of the poly(BOL) in water. Some participation mode of water molecules in polar sites, including inter- and intramolecular hydrogen bonds through amide and ether groups, along poly(BOL) chains may vary discontinuously at the temperature.
