ABSTRACT:
Ion exchanges on cellulose basis containing groups of the formula ##STR1## in which R represents a functional group and n is zero or 1 are prepared, when n is zero, by reacting cellulose or a cellulose-like compound with a .beta.-hydroxyethylsulfonyl derivative and, when n is 1, by preparing a cellulose derivative from cellulose and an amino derivative of .beta.-hydroxyethylsulfone, diazotizing the cellulose derivative and introducing R-H functional groups by coupling of ligands capable of being coupled.
