Ion-exchange behavior of carboxylate groups in fibrous cellulose oxidized by the TEMPO-mediated system

Moreover, swelling ability of the TEMPO-oxidized celluloses having various metal carboxylate groups in water and wet tensile strength of handsheets prepared thereof were studied in terms of kinds of metal ion introduced. Degree of dissociation of the metal carboxylate groups in these celluloses is likely to affect the results of the above characteristics of the TEMPO-oxidized celluloses.
