COMPOSITION FOR HYDROGEL, HYDROGEL, AND USE THEREOF

摘要

A composition for hydrogels which comprises (A1) a copolymer which comprises (a) 25 to 97 mol% structural units derived from a compound represented by formula (1) and (b) 3 to 75 mol% structural units derived from a monomer represented by formula (2) and is soluble in aqueous media and (B) a polymer which has hydrophilic groups such as hydroxyl or carboxyl groups and is soluble in aqueous media; and a hydrogel comprising the composition. (X represents a divalent organic residue; Y represents alkyleneoxy, etc.; Z, R<1>, R<2>, R<3>, R<4>, and L<2> each represents hydrogen, etc.; and L<1> represents -C6H4-, etc.)
