super absorbent polymer is a water-swollen high molecular polymer containing strong hydrophilic plymer groups, such as carboxyl and so on and certain degree of cross linking. It does not dissolve in water or organic solvent. With unique water absorbency and water retention, sap possess all the advantages of high molecular materials. Therefor, it has wide range of uses and great promise. Up to now, it has mainly been used in hygienic products(such as sanitary napkins and diapers, ects.)
