Hydrophilic copolymers and medical devices |
| abstract |
An object of the present invention is to provide a hydrophilic copolymer capable of forming a surface lubricating layer that exhibits excellent lubricity and durability (lubrication retention). In addition, a hydrophilic copolymer having good solvent solubility is provided. The solution is a hydrophilic copolymer comprising: a structural unit derived from a polymerizable monomer (A) having a sulfotrimethylammonium hydantoin structure; and a structural unit derived from a polymerizable monomer (A) The structural unit of (B), wherein the polymerizable monomer (B) has a sulfonic acid group (-SO 3 H), a sulfuric acid group (-OSO 3 H), a sulfite group (-OSO 2 H), and their at least one group from the group consisting of salt groups; and a structural unit derived from a polymerizable monomer (C) having a photoreactive group. |
