Advances in the development of water-soluble nonstoichiometric polyelectrolyte complexes, which are characterized by high stability and can be involved competitive interpolyelectrolyte reactions, summarized analyzed. The complexes remain stable over a wide range external conditions (pH, ionic strength, temperature), but show rapid, reversible highly sensitive response to environmental changes outside this changing phase state. review considers methods preparation properties formed...
Wild-growing berries of Hippophae rhamnoides L. (sea buckthorn) and Crataegus sanguinea (hawthorn) were used as plant raw materials for obtaining the extracts. Elemental analysis samples was conducted to determine content elements such nitrogen, sulfur, total carbon, organic carbon. The various chemical determined using inductively coupled plasma mass spectrometry (ICP-MS) method. Liquid extracts obtained from fruits 70% ethanol at a ratio 1:10. characterized by parameters flavonoid content,...
Abstract The interaction of poly(acrylic acid) (PAA) and poly(ethylene glycol) (PEG) with strontium ions the binding by equimolar interpolymer complexes (IPCs) PAA PEG were studied. stability constants binary polymer–metal determined. Aqueous solutions IPCs applied as soil structuring agents in model real experiments. ability to capture radioactive from polluted Semipalatinsk Nuclear Test Site was established. © 2002 Wiley Periodicals, Inc.

Excessive reservoir water poses significant challenges in the oil and gas industry by diminishing hydrocarbon recovery efficiency generating environmental economic complications. Conventional polymer flooding techniques, although beneficial, often prove inadequate under conditions of elevated temperature salinity, highlighting need for more resilient materials. In this research, two types acrylamide-based preformed particle gels (PPGs) were synthesized, as follows: polyelectrolyte...
Soil degradation is an important problem on a global scale. Suitable materials for its solution are interpolyelectrolyte complexes (IPEC) of biodegradable polymers. IPEC based the oppositely charged pairs polymers—chitosan and sodium alginate (Ch‐SA), chitosan carboxymethylcellulose (Ch‐SC), chitosan‐gellan gum (Ch‐GG) were prepared studied using different physicochemical techniques (FTIR‐spectroscopy, dynamic light scattering, conductometric turbidimetric titration, rheoviscometric...
<p>Novel linear copolymer exhibiting poly(ampholyte-electrolyte) behavior was involved into complexation reaction with anionic, cationic and nonionic polymers. Interpolymer complexes were prepared by mixing of aqueous solutions individual polymers concentration varying from 10<sup>-1</sup>-10<sup>-4</sup> mol×L<sup>-1</sup>. The formed interpolymer showed the soil structuring effect ability to extract radioactive strontium polluted topsoil...

The interpolyelectrolyte complex of the composition [chitosan]:[alginate] = [1]:[4] was prepared by mixing a hydrochloric acid solution cationic polyelectrolyte chitosan and an aqueous anionic polyelectro-lyte sodium alginate. alginate biopolymers first used as soil structurizer. Due to low humus light mechanical composition, dark chestnut dry-steppe zone East Kazakhstan region is subjected erosion. Introducing polymer into specified contributed improvement wind resistance, increase in...
