"RETICULATED POLYMER, PROCESS FOR YOUR PRODUCTION, STRUCTURE AND ABSORBENT ARTICLE AND PAPER DIAPER". A cross-linked polymer (A) comprising, as essential structural units, units derived from (a) one or more vinyl monomers selected from the group consisting of water-soluble vinyl monomers and / or vinyl monomers which become water soluble by hydrolysis and units derived from (b) a cross-linking agent and meeting the following requirements: (1) (X) <242> 25 g / g, (2) (Y) <242> 15 g / g (3) ( Y) <242> 0.54 (X) + 41. It has extraordinarily high water retention and extraordinarily high absorption capacity under load. When applied to an absorbent structure and an absorbent article, the polymer exhibits excellent absorption performance. In the ratios, (X) is the amount of physiological saline retained over 1 hour of absorption and (Y) is the amount of physiological saline absorbed over 1 hour of rest under a load of 60g / cm ^ 2 ^ . |
