Method for modifying water-soluble polymer |
| abstract |
(57) [Problem] To provide a polymer having a structural unit represented by α-hydroxyacrylic acid by a simple method. The water-soluble polymer represented by polyacrylic acid is modified into a polymer having a structural unit represented by α-hydroxyacrylic acid in the presence of a metal salt and hydrogen peroxide. Provided is a method for modifying a hydrophilic polymer. A preferable water-soluble polymer is a polymer having at least one member selected from the group consisting of residues of acrylic acid, maleic acid, fumaric acid, and maleic anhydride and salts thereof as a constituent unit. |
