  A process for preparing a water-absorbent resin made from an α,β-unsaturated carboxylic acid as an essential monomer characterized in that the process comprises allowing a metal chelating agent to be present at any step in the process in an amount of 0.001 to 6 parts by weight, based on 100 parts by weight of the α,β-unsaturated carboxylic acid; and adding a reducing agent or an oxidizing agent thereto in an amount of 0.001 to 6 parts by weight, based on 100 parts by weight of the α,β-unsaturated carboxylic acid before initiation of drying and/or during drying of a gelated product containing a water-absorbent resin obtained by polymerization.

  一种制备以α，β-不饱和羧酸为基本单体的吸水性树脂的工艺，其特征在于，该工艺包括在该工艺的任何步骤中允许金属螯合剂以0.001至6份(重量)的金属螯合剂(以100份(重量)的α，β-不饱和羧酸为基准)；以及在开始干燥含有通过聚合获得的吸水性树脂的凝胶化产品之前和/或在其干燥过程中加入还原剂或氧化剂，加入量为0.001至6份(重量)(以100份(重量)的α，β-不饱和羧酸为基准)。
