Claim 0:
1. A super absorbent polymer sheet prepared by a method comprising the steps of:
preparing a monomer composition comprising a water-soluble ethylene-based unsaturated monomer having at least partially neutralized acidic groups, a polymerization initiator, an internal cross-linking agent, a foam stabilizer, an ionic polymeric binder, and an inorganic filler;
preparing a hydrogel polymer by thermal polymerization or photopolymerization of the monomer composition;
drying the hydrogel polymer to form a super absorbent polymer; and
forming the super absorbent polymer into a sheet form,
wherein the super absorbent polymer sheet has a porosity of 25 to less than 80%.
