Аннотация: Interpolyelectrolyte complexes of a linear cationic polymer poly(diallyldimethylammonium chloride)and anionic microgel particles with carboxyl groups in a pH 6 buffer solution are presented. Dispersionsof the microgel and its complexes—negatively charged with a 3-fold molar excess of the anionic groups of themicrogel and positively charged with a 3-fold molar excess of the cationic groups of the polycation—retainaggregative stability for six months. When applying 1 wt % dispersions of the microgel and complex on thesurface of the soil with a high sand content, polymer-soil coatings with a mechanical strength of 19 to61 kg/m2 depending on the composition of the dispersion are formed. These indicators significantly exceedthose for coatings obtained by applying a 1 wt % solution of a linear anionic polymer, poly(acrylic acid), onthe soil surface. Coatings involving microgel and its complexes remain stable at an air flow rate of 190 km/h
