Abstract

It is shown that surface of the polymer phase is “bended” by adsorbate molecule, and under
certain conditions for cyclic molecules the mechanism of “absorption by a macromolecule” is realized
with dilution in liquid phase after that. This effect is conditioned by macromolecular conformational
rearranging on the surface of stationary phase and formation of spherical cavern about adsorbate molecule
in result of their sufficiently long time interaction. Theoretical conclusions demonstrated by examples of
calculations are validated by experimental data from literature.
