Studies on methoxycarbonylcellulose: Conductivity measurements of solutions, 1

The conductivity behaviour of a partially neutralized methoxycarbonylcellulose (carboxymethylcellulose, CMC) solution was investigated at different frequencies using a home made conductance bridge. The equivalent conductance of CMC solutions has very poor dependence on frequency contrary to the behaviour of simple ionic compounds. The effect of concentration on the polyelectrolyte behaviour was investigated conductometrically and it was observed that the polymer concentration has little effect on polymer charge fraction and polymer counterion fraction. Sodium ion‐binding on the polymer molecule was also investigated.
