PROBLEM TO BE SOLVED: To provide an antithrombus material using a material not including an aromatic ring, easy in synthesis, unnecessary in the surface treatment, at a low cost, and usable in various medical supplies. SOLUTION: This antithrombus material is a block copolymer consisting of a block unit derived from a ring conjugate diene monomer and a block unit derived from a chain conjugate diene monomer, and in the antithrombus material, the mean molecular weight of the copolymer is 10,000 to 500,000, and also the content of the block unit derived from the ring conjugate diene monomer is 20 to 80 wt.% and the shunt blood circulating time of the antithrombus material is at least 5 hours. |
