摘要：
The present invention relates to a super absorbent resin that has excellent initial water absorption and is watertight under pressure, even after time has elapsed, and concurrently optimizes, to predetermined ranges, centrifuge repair capability (CRC), absorbency under load (AUL), gel bed permeability (GBP), absorption rate under pressure, etc. of the super absorbent resin, thereby being capable of improving the physical properties of a final diaper, and thereby being capable of manufacturing a diaper to which ultra-thin technology has been applied. The super absorbent resin comprises: crosslinked polymers wherein a powdered base resin is surface-crosslinked by C2-8 diol or a glycol-based compound, and the powdered base resin is manufactured by polymerizing water-soluble ethylene-based unsaturated monomers including an acidic group and at least partially neutralized using two or more kinds of inner crosslinking agents.COPYRIGHT KIPO 2015본 발명은 초기 흡수성이 우수하고 시간 경과 후에도 가압시 수분이 베어나오지 않는 고흡수성 수지에 관한 것으로, 고흡수성 수지의 원심분리 보수능(CRC), 가압 흡수능(AUL), 겔 베드 투과율(GBP), 및 가압 흡수 속도 등을 소정의 범위로 동시에 최적화함으로써, 최종 기저귀에서의 물성 향상이 가능하고, 이를 통해 초박형 기술이 적용된 기저귀를 제조할 수 있다.
