Abstract

Oppfinnelsen tilveiebringer et superabsorberende material som omfatter en kombinasjon av: (1) en anionisk superabsorbent hvori fra 20 til 100 % av de funksjonelle grupper er i fri syreform, og (2) en kationisk superabsorbent hvori fra 20 til 100 % av de funksjonelle grupper er i baseform, idet den kationiske superabsorbent er basert på et polysakkarid eller en polymer av enheter av en monomer med formel (I): CHa-CH H^C N - CH-CH, I ^ CH, ^ a) hvori R^ og R^, som kan være like eller forskjellige, hver er organiske radikaler som ikke negativt påvirker egenskapene til polymeren, og hvor X er et passende anion. Kombinasjonen er særlig effektiv som en superabsorbent i forbindelse med elektrolyttholdige løsninger som menstruasjonsvæsker og urin.The invention provides a superabsorbent material comprising a combination of: (1) an anionic superabsorbent wherein from 20 to 100% of the functional groups are in free acid form, and (2) a cationic superabsorbent wherein from 20 to 100% of the functional groups are in base form, the cationic superabsorbent being based on a polysaccharide or polymer of units of a monomer of formula (I): CH 2 -CH H 2 CN - CH-CH, 1 , which may be the same or different, each are organic radicals that do not adversely affect the properties of the polymer, and where X is a suitable anion. The combination is particularly effective as a superabsorbent in connection with electrolyte-containing solutions such as menstrual fluids and urine.
