Abstract

Physico-chemical interactions between sodium alginate (ALG-Na), polyvinylpyrrolidone (PVP), sodium carboxymethylcellulose (CMC-Na) and solvent were examined. The performed studies involve effect of concentration of macromolecule compounds, electrolytes and pH value of the system. Non-Newtonian system were described by pseudoplasic coefficient and thixotropic coefficient - B and M. These coefficients allow to estimate quantitatively rebuilding of macromolecular structure.
