Rheological behaviour of carboxymethylcellulose manufactured from TCF-bleached Milox pulps

Carboxymethylcellulose (CMC) samples with different degrees of substitution were obtained from Eucalyptus globulus pulps made in formic acid-peroxyformic acid medium (Milox delignification) and subjected to Totally Chlorine Free bleaching. In order to assess the rheological behaviour of the synthesized materials, their properties (rheological behaviour, solubility and molar mass) were determined and examined in relation to their total degree of substitution. Additional discussion on the structure and purity of pulps, alkali celluloses, and CMC is provided.
