Abstract: A highly absorbent polymer comprises water-insoluble, hydrophilic, crosslinked polymer particles having carboxyl or carboxylate groups, characterised in that said water-insoluble, hydrophilic, crosslinked polymer particles have an absorbing capacity satisfying the following requirements (i) to (iii), said absorbing capacity being imparted by enhancing the crosslinking density of the surfaces of said Water-insoluble, hydrophilic, crosslinked polymer particles: (i) the equilibrium swelling physiological saline absorption is 40 g/g (polymer) or more; (ii) the physiological saline absorption is 3 ml or more as determined by swelling 0.3 g of the polymer with physiological saline for 10 sec; and (iii) the time taken for 5ml of physiological saline to pass through a cylinder (internal diameter: 10mm) having a cross- sectional area of 0.785 cm is 40 sec or less after 0.05 g of the polymer is packed together with physiological saline into the cylinder and swollen with the physiological saline, reaches an equilibrium swelling physiological saline absorption and settles in a swollen state.

Abstract: This invention provides a method of manufacturing polymer particles of indeterminate form, characterized in that a cationic surface active agent or an amphoteric surface active agent is present as a dispersant when a water-soluble polymerizable monomer is polymerized by using an inert hydrophobic organic solvent and an aqueous solution of the water-soluble polymerizable monomer. According to the manufacturing method of the present invention, polymer particles of indeterminate form useful as a water absorbing resin having a low apparent specific gravity, a high water absorption degree including a high initial water absorption rate, a high gas-permeability, a high liquid-permeability and a high post-water-absorption gel strength, and, especially, as a water absorbing resin for the production of an absorption body for a sanitary material contacting a human body, such as a sanitary napkin, a paper diaper, shorts for adults, a tampon and sanitary cotton can be obtained by a simple operation with a high productivity and on a mass-production basis.
