PROBLEM TO BE SOLVED: To provide a cured product (for example, a film), in which the balance between hydrophilicity and abrasion resistance is superior, decrease in hydrophilicity due to water is minimal, and the weather resistance is also superior, as well as a method for preparing a polymer and a polymer composition that can yield such a cured product.SOLUTION: The present invention provides a polymer, in which a specific copolymer (i) having a sulfonic acid-containing group, an epoxy group, and a specific alkoxysilyl group in a molecule is prepared from a specific monomer mixture.SELECTED DRAWING: None |
