FIELD: polymers.
SUBSTANCE: invention relates to powder-like cross-linked products absorbing different liquid and based on partially neutralized, ethylene-unsaturated and comprising acidic groups of monomers. Invention proposes a powder-like polymeric product subjected for additional cross-linking and absorbing water, aqueous or serosa liquid and blood that is synthesized from: (a) polymerized ethylene-unsaturated and comprising acid groups of monomers neutralized by at least 25 mole%, 55-99.9 wt.-%, and (b) polymerized ethylene-unsaturated copolymerized with monomers of (a) monomers, 0-40 wt.-%; (c) one or some polymerized cross-linking agents, 0.1-5.0 wt.-%, and (d) water-soluble polymer, 0-30 wt.-%. Proposed product possesses the more effective properties being first of all the better capacity for transfer of absorbed liquids in a swollen state. Product can be subjected for surface cross-linking using a combination consisting of an organic cross-linking compound but with exception of polyols and cation as its salt in an aqueous solution. Also, invention proposes a diaper and hygienic article for adults based on the claimed product.
EFFECT: valuable properties of product and articles.
