Patent ID: 7838155

Claim:
A method for producing an aqueous electrolyte solution absorber comprising the steps of: placing, in a water permeable unit, (1) at least two layers of an aqueous electrolyte solution absorbent polymer obtained by introducing a hydrophilic group to a water insoluble polymer including at least one or more kinds of aromatic rings and/or conjugated dienes in a principal chain and/or a side chain, and (2) a solid material spacer in-between the layers of aqueous electrolyte solution absorbent polymer effective to create a space in-between the layers of the aqueous electrolyte solution absorbent polymer; and absorbing a liquid with the aqueous eletrolyte solution adsorbent polymer causing the aqueous electrolyte solution absorbent polymer to swell and thereby reducing the space in-between the layers of the aqueous electrolyte solution absorbent polymer created by the solid material spacer, wherein, a flexible network support member is located within each layer of aqueous electrolyte absorbent polymer, the flexible network support member effective to support the aqueous electrolyte absorbent polymer.
