Abstract:
An antithrombotic surface treating agent comprising a copolymer comprising a first monomer of formula (1) and a second monomer which is at least one monomer selected from the group consisting of monomers of formulae (2), (3), (4) and (5), as monomer components, wherein the molar ratio of the first monomer to the second monomer is 85/15 to 99.9/0.1, wherein the copolymer has a number based mean molecular weight of 5,000 to 500,000; wherein R1 is an alkylene group having 1 to 4 carbon atoms, R2 is an alkyl group having 1 to 4 carbon atoms, and R3 represents hydrogen or a methyl group, wherein each R4 independently represents hydrogen or an alkyl group having 1 to 4 carbon atoms, R5 independently represents hydrogen or a methyl group, n is an integer of 1 to 4, and Xâ€” independently represents an anion derived from halogen, sulfonic acid or sulfuric acid.
