(57) Abstract: Biocompatible diols, polyurethanes, A method for producing the diol, a method for producing the polyurethane, and use as a blood-compatible material. [Wherein, R 1 represents a hydrogen atom or an alkyl group having 1 to 18 carbon atoms, m 1, m 2 and m 3 represent an integer of 1 to 6 and may be the same or different; Sug. Is a residue of any of monosaccharides, oligosaccharides and polysaccharides in which hydroxyl groups are acylated. ｝] A saccharide residue-containing diol represented by the formula: And a polyurethane hydrolyzate obtained by addition polymerization of the diol with a diisocyanate. A biocompatible material using the polyurethane. |
