More Information
Summary:The present invention provides a method for highly efficiently producing a water-soluble polymer and a method for producing a water-absorbing resin having excellent ability to absorb water. The method for producing a water-soluble polymer comprises step (a1) in which starch is reduced in molecular weight to thereby obtain a partial-starch-decomposition product and step (a2) in which an ionic functional group is introduced into the partial-starch-decomposition product obtained in the step (a1).
