Initial Rates of Flocculation of Polystyrene Latex with Polyelectrolyte - Effect of Ionic-Strength
The rate of flocculation of polymer latices immediately after the addition of polyelectrolyte was measured by applying the standardized procedure of colloid mixing. It was found that the rate of flocculation in the initial stage is remarkably enhanced by the addition of polyelectrolyte and that the extent of this enhancement decreases with an increase in the ionic strength. The conformation of polyelectrolyte in the solution is considered to have a direct influence on this result.
