Abstract
A polymer in the form of particles is water-insoluble and water-sellable, containing carboxyl or carboxylate groups. It has a physiological saline absorption quantity of 40 to 90 grams per one gram of the polymer, a physiological saline absorption rate of at least 8 ml per 0.3 gram of the polymer, a gel strength of 33 to 200 g/cm2 when it has been swollen to saturation with ion-exchange water. It is useful as an absorbent in a sanitary article.
