| abstract |
A copolymer 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. The copolymer includes monomer unit A, monomer unit B, and monomer unit C, wherein monomer unit C has a mole fraction of 0.5-40% with respect to the total amount of all constituent monomer units. |
