Claim Text:
1. A super absorbent polymer, comprising: surface crosslinked polymer particles prepared by surface crosslinking of particles of a base resin, wherein the base resin is polymerized from a monomer composition including water-soluble ethylene-based unsaturated monomers; and a water-soluble component, wherein the water-soluble component has a ratio (dwt/d(log M)) of 0.9 or less over molecular weights (M) ranging from 100,000 to 300,000 when measured from an eluted solution after swelling 1 g of the super absorbent polymer in 200 ml of 0.9% NaCl solution at 25° C. for 1 hour, and wherein the content of the water-soluble component is 2.5 to 5% by weight, based on the total weight of the super absorbent polymer, when measured after swelling the super absorbent polymer for 1 hour.
