Document Type and Number:
WIPO Patent Application WO/2020/213529
Kind Code:
A1
Abstract:
The present disclosure provides an antithrombogenic material having a substrate and a surface modified layer provided on at least a portion of the substrate, wherein: the surface modified layer includes a block copolymer having a first structural unit having, in the side chain thereof, at least one selected from the group consisting of an alkylene chain and a halogenated alkylene chain, and a second structural unit represented by general formula (1); a unit including the first structural unit has a weight average molecular weight of 9,000-15,000; and a unit including the second structural unit has a weight average molecular weight of 10,000-40,000. In general formula (1), R1 represents a hydrogen atom or a methyl group, R2 represents a methyl group or an ethyl group, n represents an integer of 1-6, m represents an integer of 1-100, and x represents an integer of 1 or more.
