<p>A polysaccharide derivative wherein a part or the whole of the hydrogen atoms of the hydroxyl groups of a polysaccharide or a derivative thereof are substituted by all of a group (A): -X-R1, a group (B): -X-R2, and a group (C): -Y-Z, or by both of groups (B) and (C) and the average degree of substitution per constituent monosaccharide unit is 0 to 0.1 for the group (A), 0.0001 to 0.2 for the group (B), and 0.001 to 1.0 for the group (C); wherein X represents a single bond, an alkylene or oxyalkylene group having 1 to 3 carbon atoms and optionally substituted by -OH, or carbonyl; R1 represents an alkyl or alkenyl group having 4 to 40 carbon atoms; R2 represents an alkyl or alkenyl group having 4 to 40 carbon atoms, with a part or the whole of the hydrogen atoms being substituted by a fluorine atom; Y represents an alkylene group having 1 to 5 carbon atoms and optionally substituted by -OH; and Z represents -COOH, -SO¿3?H, or a salt thereof.</p> |
