The present invention provides a copolymer with sufficient biocompatibility for medical material applications; and a method for forming a crosslinked body that uses the copolymer to impart biocompatibility to the surface of a substrate. Specifically, the protein adsorption inhibitory effect and the cell adhesion inhibitory effect are imparted to the surface of the substrate as a phosphorylcholine group. The inventors of the present invention found that copolymers containing phosphorylcholine structural units and photoreactive structural units, or copolymers containing phosphorylcholine structural units, photoreactive structural units, and hydrophobic structural units, can be irradiated by light Such a simple method imparts a protein adsorption inhibitory effect and a cell adhesion inhibitory effect to the surface of the substrate, thereby completing the present invention. |
