POLYMER AND CROSSLINKED BODY THEREOF

摘要

The present invention addresses the problem of providing a copolymer having sufficient biocompatibility for use in medical material applications, and also providing a method for forming a crosslinked body, wherein said copolymer is used to modify a substrate surface so as to be biocompatible. More specifically, the present invention imparts a protein adsorption suppressing effect and a cell adhesion suppressing effect, which are features of a phosphorylcholine group, to a substrate surface.　A copolymer containing, at a specific ratio, a phosphorylcholine structural unit, a hydrophobic structural unit, and a photoreactive structural unit was found to solve the above problem, thus completing the present invention.
