Notes:
Suspensions of microcrystalline cellulose particles were flocculated with two cationic ionene polymers differing only in charge density. A comparison of the flocculation (residual absorbance) and electrophoretic data showed that optimum destabilization corresponded to neutralization of the particle charge and that both polyelectrolytes had the same flocculating ability on a charge basis. These results, when combined with specific adsorption measurements, suggest that flocculation of the cellulose particles is accomplished by a recently proposed, “mosaic” charge neutralization mechanism.
