Abstract
Electrolyte concentration, rather than pH, concentration of resin particles, or dispersity, is the most significant variable affecting the mobility of polyvinyl acetate emulsions. The mobility–electrolyte concentration curves for latices prepared with nonionic and mixed nonionic and anionic emulsifiers, indicate micelle formation at low electrolyte concentrations. Zeta potentials calculated for a typical latex show the potential drop in the double layer to be of the order of 10−7volts for a variation of thickness of the ionic atmosphere from 10−5to 10−6 cm. over the range of salt concentration used.
