ABSTRACT:
The present invention is to provide a super-absorbent resin which can be used to design an absorbing core or absorbing goods capable of being flown into a flushing toilet. The present invention relates to a super-absorbent resin having as a main component thereof a repeating unit having an ionic dissociation group in its main or side chain, wherein said resin has absorption capacity without load to saline solution (CRCs) for 4 hours of not smaller than 10 g/g, and solubility in ion-exchanged water of not lower than 50% by weight.
