A crosslinked polymer (A) which comprises, as essential structural units, units derived from (a) one or more vinyl monomers selected from the group consisting of water-soluble vinyl monomers and/or vinyl monomers which become water-soluble upon hydrolysis and units derived from (b) a crosslinking agent and which satisfies the following requirements: (1): (X) ≧ 25g/g, (2): (Y) ≧ 15g/g, and (3): (Y) ≧ -0.54 (X) + 41. It has exceedingly high water retentivity and exceedingly high absorbing power under load. When applied to an absorbent structure and an absorbent article, the polymer has excellent absorbing performance. In the relationships, (X) is the amount of physiological saline retained through 1-hour absorption and (Y) is the amount of physiological saline absorbed through 1-hour standing under a load of 60 g/cm2.
一种交联聚合物(A),其基本结构单元包括(a)一种或多种乙烯基单体衍生的单 元,这些乙烯基单体选自由水溶性乙烯基单体和/或水解后变成水溶性的乙烯基单体 组成的组,以及(b)一种交联剂衍生的单元,并满足以下要求:(1):(X) ≧ 25g/g, (2):(Y) ≧ 15 克/克,及 (3):(Y) ≧ -0.54 (X) + 41。它具有极高的保水性和极高的负载吸附力。当应用于吸水结构和吸水物品时,该聚合物具有优异的吸水性能。在上述关系中,(X) 是在 60 克/平方厘米的负载下,通过 1 小时的吸收所保留的生理盐水量,(Y) 是在 60 克/平方厘米的负载下,通过 1 小时的静置所吸收的生理盐水量。
