Modified cellulose for biocompatible dialysis membranes IV and process for production thereof

摘要

Modified cellulose for biocompatible dialysis membranes which has a structure represented by the formula <IMAGE> in which Cell is cellulose or chitin, in each case without hydroxyl groups, s is 3 in the case of cellulose and 2 in the case of chitin, and R' is CH3 and/or C2H5 and/or C3H7, X is defined functional groups, and Z corresponds to the following groups of atoms: SR'', SO3H (salt), SO-R, SONR''2, SO2-R, SO2NR''2, SO2H (salt), F, Cl, Br, I, NR''2 , PR''2, PO3H2 (salt), PO2H(OR), PO(OR)2, PO2HR'' (salt), POR''(OR), POR''2 R'' is H or R, x + t is 0.75-2.85 t is 0-2.85, x is 0-2.85 z is 0.01-0.45. A process for the production of the modified cellulose is also claimed.
