PROBLEM TO BE SOLVED: To provide a manufacturing process of a water-absorbing resin which comprises reacting an alkali metal hydroxide with a copolymer of at least one kind of monomer selected from the group consisting ofα-olefins and vinyl compounds and maleic anhydride or a maleate and subjecting 100 pts.wt. of the reaction product to crosslinking reaction with 14-30 pts.wt. of a polyvalent epoxy compound. SOLUTION: The water-absorbing resin obtained has a high water-absorbing rate and a high water-releasing rate on drying, is durable to cleaning and to drying in the sun and with dryers and allows repetitive use.
