摘要： A method for producing a cross-linked polymer manifesting a high absorption capacity and having a small content of soluble component by a convenient and expeditious process with high productivity is provided. An absorbent resin such that disposable diapers and other products incorporating the absorbent resin manifest outstanding qualities and a method for the production of the absorbent resin are proposed. The cross-linked polymer according to this invention is produced by a method of polymerizing an aqueous polymerizable monomer solution containing a water-soluble ethylenically unsaturated monomer and a first cross-linking agent capable of forming a hydrogel polymer by polymerization, which method comprises the steps of performing the polymerization in a substantially static state from the time at which the polymerization is initiated till the time at which the whole polymerization system is gelated, subsequently giving the polymerization system a thorough shearing force thereby granulating the hydrogel polymer before the polymerization system has the temperature thereof elevated by the heat of polymerization to the highest level, and further continuing the polymerization.

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.
