Abstract
Recently, it was shown (1) that the adsorbed emulsifier and solute electrolyte are removed quantitatively from polystyrene latexes by ion exchange. Rigorous purification of the ion-exchange resin is necessary to avoid contamination of the latex by leached polyelectrolytes. The ion-exchanged latexes are titrated conductometrically with sodium hydroxide to determine the residual charged groups on the particle surface. These strong-acid groups are attributed to the sulfate endgroups of the polymer molecules introduced by the persulfate initiator.
