    摘要: There is disclosed a process to uniformly and rapidly carry out the mixing of a monomer liquid and a polymerization initiator and thus for the resulting polymer not to adhere to the inner surface of the piping or the inside of the apparatus in an art of producing a water-absorbent resin by continuously mixing the monomer liquid and the polymerization initiator together and thereby carrying out polymerization. This process comprises the steps of: (a) continuously supplying a monomer liquid 20 to such as a supply pipe 10 to continuously stir the monomer liquid 20 in the supply pipe 10 with such as a stirring apparatus 12; (b) causing a polymerization initiator 30 to join into a flow of the monomer liquid 20 being in a stirred state, thereby obtaining a mixed liquid 40 of the monomer liquid 20 and the polymerization initiator 30; and (c) continuously supplying the mixed liquid 40 from the supply pipe line 10 to a polymerization apparatus to cause the mixed liquid 40 to run a polymerization reaction.

    摘要: An object of the present invention is to provide a water absorbent having excellent gel properties and showing excellent properties when used in a water-absorbing material of a sanitary/hygienic material such as paper diaper. Moreover, another object of the present invention is to provide a water absorbent which is safe and excellent in liquid permeability, and in which an amount of liquid permeability improver for improving the liquid permeability is reduced. The water absorbent is made from a water-absorbing resin prepared by a specific polymerization method and having a high degree of cross-linking, a high liquid holding property and a high gel strength (its swelling pressure of gel layer of is 35 kdyne/cm2 or more). This water absorbent is further processed to have a particular particle size distribution (95 wt % or more of its particles are less than 850ƒÊm but not less than 106ƒÊm, and logarithmic standard deviation (ƒĐƒÄ) is in a range of 0.25 to 0.45) and then surface cross-linked. After that, a liquid permeability improver is added therein.
