<p>A cellulosic polymer wherein at least a part of the hydroxyl groups of the cellulosic polymer is modified as represented by the following general formula [I]: <CHEM> wherein R<1> and R<2> may be the same or different and each represents a hydrogen atom or a C1 to C5 alkyl group, X is a strong negative atomic group, and Y is <CHEM> wherein R<3> and R<4> may be the same or different and each represents a member selected from the group consisting of a hydrogen atom, a C1 to C5 alkyl group and a C3 to C6 cycloalkyl group, or Y is <CHEM> wherein R<5>, R<6> and R<7> may be the same or different and each represents a member selected from the group consisting of a hydrogen atom, a C1 to C5 alkyl group, a C3 to C6 cycloalkyl group and a C6 to C10 aryl group, and n is from 1 to 10. Using the cellulosic polymer, a blood-treating device is assembled.</p> |
