An antithrombotic resin comprising polyurethane or polyurethaneurea prepared by using at least one polyetherdiol selected among polyols containing a polyoxyethylene group represented by general formula (I), wherein n represents a number-average degree of polymerization of 1 to 100, and polyols containing a polyoxytetramethylene group represented by general formula (II), wherein m represents a number-average degree of polymerization of 1 to 100, and one or more antithrombotic agents. The resin can release the antithrombotic agent(s) into blood at high concentration for long. Antitrhrombotic tubes, films and coatings can be produced from this resin. |
