FIELD: chemical compositions, polymers.
SUBSTANCE: invention relates to aqueous compositions comprising particles of chemically cross-linked water-soluble or water-dispersed chemical microgel. Invention proposes an aqueous composition comprising particles of chemically cross-linked water-soluble or water-dispersed chemical microgel bound with at least one bridge water-soluble or water-dispersed polymer wherein its chemical composition differs from chemical composition of indicated particles. The amount of chemical microgel particles is from 0.05 to 40% dry mass of the composition mass, and the amount of bridge polymer provides exceeding the viscosity value of the composition by at least three times or preferably it exceeds or equal to 10-fold viscosity value of chemical microgel particles an aqueous solution, and exceeds viscosity value of the bridge polymer an aqueous solution under the same conditions. Also, invention proposes a method for preparing of the claimed an aqueous composition. Proposed composition can be used in the field for mining petroleum and gas deposits, and in manufacturing detergents and cosmetics also. Invention provides enhancing stability of the composition.
EFFECT: improved and valuable properties of composition.
