Abstract

The carboxymethylation of bacterial cellulose (BC) was studied under typical heterogeneous reaction conditions. It was found that the BC possesses a significantly lower reactivity compared to wood cellulose converted under comparable conditions. Moreover, water-solubility of carboxymethyl cellulose (CMC) obtained from BC appears at rather high degree of substitution of about 1.5 although a nearly statistical functionalization pattern was analyzed by HPLC. Obviously, the nano-structure of BC is important for the reactivity and the properties of the synthesized CMC like water-solubility.
