Sorption of solutions complicated by the crystallization of a polymer sorbent

The sorption of a liquid polymer solution have been studied as a function of experimental conditions, and the experimental results are discussed taking into account the chemical nature of the sorbate and the sorbent and the structure of the polymer. An algorithm of successive actions is given; it shows the effect of the structure of aqueous organic solutions on their sorption by semicrystalline polyethylene terephthalate.
