Для синтезированных сополимеров определены гидродинамический радиус и сегмент Куна, характеризующий гибкость полимерной цепи, константа Хаггинса в водном и солевом растворах, концентрационные области формирования надмолекулярных структур. В присутствии катионного ПАВ (бензетония хлорид, Hyamine) в зависимости от концентрации сополимеров в системе образуются комплексы «полимер–ПАВ» в растворимой и нерастворимой формах. Показано, что эффективность стабилизирующего действия растворимых комплексов в отношении водной дисперсии карбоната кальция возрастает с увеличением содержания неполярных групп в полимерной цепи. Катионный ПАВ (Hyamine) предложен в качестве осадителя в методе количественного определения карбоксилсодержащих полимеров в водной и солевой средах. </p></abstract><trans-abstract xml:lang="en"><p>Copolymers of methacrylic acid and natural terpene monomers (α-pinene; β-pinene; ∆3-karene) with the molecular weight of (0.3–0.5)∙104 and a content of carboxyl groups of 14.5–16.3 % were synthesized. For the synthesized copolymers, hydrodynamic radius and the Kuhn segment, which characterizes flexibility of a polymer chain, were determined, as well as the Huggins constant in aqueous and saline solutions, and concentration regions for formation of supramolecular structures. In the presence of a cationic surfactant (benzetonium chloride, Hyamine), depending on the concentration of copolymers in the system, polymer-surfactant complexes were formed in soluble and insoluble forms. It has been shown that the effectiveness of the stabilizing action of soluble complexes with respect to an aqueous dispersion of calcium carbonate increases with an increase in the content of nonpolar groups in the polymer chain. A cationic surfactant (Hyamine) has been proposed as a precipitant in the method for the quantitative determination of carboxyl-containing polymers in aqueous and saline media. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>синтез</kwd><kwd>сополимер</kwd><kwd>метакриловая кислота</kwd><kwd>терпен</kwd><kwd>поверхностно-активное вещество</kwd><kwd>реология</kwd><kwd>устойчивость дисперсии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>synthesis</kwd><kwd>copolymer</kwd><kwd>methacrylic acid</kwd><kwd>terpene</kwd><kwd>surfactant</kwd><kwd>rheology</kwd><kwd>stability of dispersion</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">Фрог, Б.
