摘要：
A water absorbing agent comprising a crosslinked polymer including a water-soluble vinyl monomer (a1) and/or a vinyl monomer (a2) that is formed into the water-soluble vinyl monomer (a1) by hydrolysis, and a crosslinking agent (b) as an essential constituting unit, wherein the following formulae (1) and (2) are satisfied; a process for its production, and absorbers and absorbent articles made by the water absorbing agent. (Y)≧−1.14(X)+69.5 (1) (X)=((x1)2+4×(x2)2)1/2 (2) wherein (x1) denotes a water-retention amount (g/g) of the water absorbing agent after being soaked in a physiological saline for one hour; (x2) denotes an absorption amount (g/g) of the water absorbing agent after being soaked in a physiological saline under loading of 0.9 psi for one hour; and (Y) denotes a liquid permeation speed (ml/min) of a physiological saline after the water absorbing agent is soaked in a physiological saline under loading of 0.3 psi for one hour. The water-absorbing agent enables easy production of absorbent articles exhibiting high absorption performance in any state, and is suitable for use in disposable diapers, sanitary napkins, and other sanitary goods.
摘要（中）：
包含通过水解形成在水溶性乙烯基单体（a1）中的水溶性乙烯基单体（a1）和/或乙烯基单体（a2）的交联聚合物和交联剂（b）的吸水剂， 作为基本构成单元，其中满足下式（1）和（2）; 其制造方法，由吸水剂制成的吸收体和吸收性物品。 （Y）> = - 1.14（X）+69.5（1）（X）=（（x1）2 + 4x（x2）2）（1/2）其中（x1） 在生理盐水中浸泡1小时后的吸水剂的保留量（g / g） （x2）表示在0.9psi负载下在生理盐水中浸泡1小时后吸水剂的吸收量（g / g） 和（Y）表示在0.3psi负载下将吸水剂浸泡在生理盐水中1小时后的生理盐水的液体渗透速度（ml / min）。 吸水剂能够容易地生产在任何状态下表现出高吸收性能的吸收制品，并且适用于一次性尿布，卫生巾和其它卫生用品。
