POWDERED WATER-ABSORBING AGENT, CONTAINING WATER-ABSORBING RESIN AS BASIC COMPONENT Russian patent published in 2009 - IPC C08F20/06 C08L101/14 A61L15/60 C08F8/14 C08J3/205 

FIELD: chemistry.

SUBSTANCE: versions are proposed of a powdered water-absorbing agent, which contains a powdered water-absorbing resin, obtained from a polymer based on partially neutralised polyacrylic acid. The surface of the said powdered water-absorbing resin is cross-linked with at least one cross-linking agent, chosen from a group comprising glycerin, 1,3-propanediol, ethylene carbonate, 3-ethyl-3-hydroxymethyloxetane and ethanolamine. The said water-absorbing resin has a cross-linked internal structure. Content of the said powdered water-absorbing resin is between 70 and 100 wt % per 100 wt % of the said powdered water-absorbing agent. The said powdered water-absorbing agent satisfies several conditions for particle size and sorption characteristics. Proposed also is a method of obtaining a powdered water-absorbing agent and an absorbent structure based on the said agent.

EFFECT: higher absorption capacity compared to traditional absorbent structure and odour reduction.
