Abstract

In this paper, the interaction of technical and purified Carboxymethylcellulose macromolecules with solvent molecules with the same degree of exchange and polymerization is comparatively studied The thermodynamic parameters of technical and purified Carboxymethylcellulose samples were evaluated by sorption of solvent vapors. As a result of the removal of additional salts from the technical Carboxymethylcellulose, it was found that the specific surface area of the cleaned product is slightly reduced, leading to a sharp increase in the volume and radius of the pores.
