The purpose of the present invention is to provide: a copolymer that is capable of being immobilized on a base material while maintaining a high antithrombotic property persistently without having to introduce heparin or an anticoagulant drug to the surface thereof; and a medical material using same. Provided is a copolymer that comprises monomer unit A, monomer unit B, and monomer unit C represented in in chemical formula 1, wherein monomer unit C has a mole fraction of 0.5-40% with respect to the total amount of all constituent monomer units.
                            本发明的目的是提供一种共聚物,它能够固定在基底材料上,同时无需在其表面引入
肝素或抗凝血药物就能持续保持较高的抗血栓性能;以及一种使用该共聚物的医用材料。本发明提供了一种共聚物,它由
化学式 1 所表示的单体单元 A、单体单元 B 和单体单元 C 组成,其中单体单元 C 相对于所有组成单体单元总量的摩尔分数为 0.5-40%。
