Определена область неперекрывающихся клубков между концентрацией кроссовера и концентрацией образования флуктуационной сетки зацеплений и показано, что с увеличением концентрации соли эта область практически исчезает, то есть изменение механизма массопереноса происходит вблизи концентрации кроссовера. Установлено, что при низких концентрациях хлорида калия увеличение содержания ионогенных групп в макромолекулах приводит к повышению эффективного объема и снижению концентрации кроссовера. Отмечено снижение адсорбционной емкости каолина при адсорбции полимеров из солевого раствора, при этом константа адсорбции значительно выше в присутствии соли, чем в воде.</p></abstract><trans-abstract xml:lang="en"><p>Rheological properties and concentration cross-overs of anionic acrylamide copolymers in saline solutions (potassium chloride) were investigated by using capillary viscometer method. Area of non-overlapping coils between the crossover concentration and the concentration of fluctuation mesh formation was determined; it was shown that with increase of salt concentration this area practically disappears, i.e. mass transfer mechanism changes near the crossover concentration. It was shown that at low concentrations of potassium chloride increasing the content of ionic groups of macromolecules leads to reduction in the crossover concentration and increase in the effective volume. It is found that the kaolin adsorption capacity decreases when polymers are adsorbed from saline solution, and the adsorption constant is significantly higher in the presence of salt than in water.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анионный сополимер акриламида</kwd><kwd>солевой раствор</kwd><kwd>вязкость</kwd><kwd>макромолекула</kwd><kwd>эффективный объем</kwd><kwd>адсорбция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anionic acrylamide copolymer</kwd><kwd>saline solution</kwd><kwd>viscosity</kwd><kwd>macromolecule</kwd><kwd>effective volume</kwd><kwd>adsorption</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Танганов, Б.
