    Effect of the pH of the medium, temperature, and nature of solvents and inorganic salt on the behavior of hydrogels based on copolymers of poly(ethylene glycol) maleate with acrylic and methacrylic acids and acrylamide was studied. It was shown experimentally that the susceptibility of the hydrogels to changes in the factors mentioned above, depending on the nature of a comonomer.

    As a result of the remote interaction of the studied hydrogels, their mutual activation occurs, leading to a significant change in their electrochemical and conformational properties. At certain ratios of acidic and basic hydrogels, there is a significant increase in the sorption of neodymium ions compared to the original hydrogels. These results indicate the emergence of ionized structures with optimal conformation. References [1] Alimbekova B.T., Korganbayeva Zh.K., Himersen H., Kondaurov R.G. and Jumadi- lov T.K. // J.

    The mutual activation of polymer meshes in the intergel system was studied in order to identify the absorbing abilities and selectivity of hydrogels. An intergel system consisting of KU-2-8 cationite (swell) and AB-17 anionite (swell) was chosen as the object of research. it was Found that as a result of the remote action of hydrogels, mutual activity occurs, leading to significant differences in their electrochemical and conformational composition.

    The extraction of yttrium ions by interpolymer systems based on industrial ionites: KU 2-8 cationite and AB-17 anionite was studied. The dependences of the yttrium content in the aqueous medium after sorption by the interpolymer system were studied KU 2-8:AB17-8 depending on the time, the degree of binding of the polymer chain (with respect to yttrium ions) by the initial ionites and interpolymer systems KU 2-8: AB-17-8. The maximum content of yttrium ions in the aqueous medium after sorption is observed at ratios of 3:3 and 4: 2 and the duration of remote interaction is 88 hours. At the same time, the content of yttrium in the aqueous medium after sorption is 60 mol.% and 56.4 mol.%, respectively. High values of the degree of binding of the polymer chain with respect to yttrium are observed at the ratios KU 2-8: AB-17-8=3:3 References [1] Jumadilov T.K., Abilov Zh.A., Kaldayeva S.S., Himersen H., Kondaurov R.G.

    In this work, a hydrogel system was produced via radical polymerization of N,N-dimethylacrylamide and 2-acrylamido-2-methylpropanesulfonic acid in the presence of N,N-methylene-bis-acrylamide as a crosslinker and ammonium persulfate as an initiator. Parameters that impact the conversion of copolymerization (such as initial concentration of monomers, temperature, initiator dose, and time) were studied. The swelling degree of the hydrogel was investigated with the addition of a crosslinker and initiator at different pH levels. A hydrogel with high conversion and high swelling degree was selected to investigate their ability for adsorption of Pb(II) ions from solutions. Adsorption behavior of Pb(II) ions in a hydrogel was examined as a function of reaction time and concentration of lead ions from a solution of Pb(II) ions.

    Scientists have been encouraged to find different methods for removing harmful heavy metal ions and dyes from bodies of water. The adsorption technique offers promising outcomes for heavy metal ion removal and is simple to run on a large scale, making it appropriate for practical applications. Many adsorbent hydrogels have been developed and reported, comprising N,N-dimethylacrylamide (DMAA)-based hydrogels, which have attracted a lot of interest due to their reusability, simplicity of synthesis, and processing. DMAA hydrogels are also a suitable choice for self-healing materials and materials with good mechanical properties. This review work discusses the recent studies of DMAA-based hydrogels such as hydrogels for dye removal and the removal of hazardous heavy metal ions from water. Furthermore, there are also references about their conduct for self-healing materials and for enhancing mechanical properties.
