In connection with this, it adsorbent, that adsorption from solutions of polymer mixseems very interesting to compare the adsorption of polytures depends both on the miscibility of polymers in solution mers from their mixture under conditions in which the solu-(on parameters of thermodynamic interaction, x 23 ) and on tion is one phase or, under the given conditions, separates solution concentration.…”
