Notes:
The rheological properties of aqueous dispersions of hydrolyzed polyacrylonitrile-grafted cellulose (H-CPAN) have been investigated. The experimental results are consistent with the idea that the elementary particle is a rigid cellulose protofibril stabilized in suspension by associated polyelectrolyte side chains (polyacrylamide-polyacrylic acid copolymer grafts). The behavior of intrinsic viscosity with electrolyte concentration, the concentration depependence and shear dependence of the viscosity and of the steady-state and dynamic shear moduli are qualitatively explained on this basis.
