Sorption Chromatography of Polar Substances on Polyamides

Nature volume 176, pages 70–71 (1955)Cite this article

Abstract

LINEAR polyamides, in the form of fibres or fine powders, are able to absorb polar substances from solution1, with the formation of hydrogen bonds. The sorption is restricted to the amorphous regions, where a solution process of the polar substance into the polymer takes place. The Flory–Huggins relation2: has been found1 to hold, when the volume fractions v 1 and v 2 of the polymer and the polar substance are corrected for the degree of crystallinity of the polymer.
