Super absorbent polymer and method of preparing the same

A super-absorbent polymer satisfying Equation 1 exhibits remarkably improved shape rupture under pressure while maintaining excellent absorption ability. The super-absorbent polymer may be prepared by preparing a base resin by polymerizing a polymeric compound containing an acrylic monomer by using...

description	A super-absorbent polymer satisfying Equation 1 exhibits remarkably improved shape rupture under pressure while maintaining excellent absorption ability. The super-absorbent polymer may be prepared by preparing a base resin by polymerizing a polymeric compound containing an acrylic monomer by using a polyfunctional nitroxide mediated radical polymerization initiator, substituting a terminal of the polymer prepared in the polymerization step with maleic anhydride, cross-linking each maleic anhydride terminal of different polymers prepared in the substitution step by using alkylenediamine having 2 to 8 carbon atoms, drying and grinding the base resin, and surface cross-linking the ground base resin.
