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.
