Surfactant latex

It is well known (3,5,6) that sodium lauryl sulfate interacts with some polymers such as polyvinyl acetate causing solubilization of the insoluble polymer leading to an increase in viscosity. In Figure 3, viscosity of the homopolymer and 70/30 VA/BA at various NaLS/polymer ratio is shown. It is seen that the viscosity of the 2% latex dispersion increases with increase in NaLS/polymer ratio. Similar visoosity data for the 85/15 VA/BA was intermediate between the homopolymer and 70/30 VA/BA latexes. Surfactants that showed a normal saturation type adsorption behavior did not show any significant visoosity increase of the latex.

Formulations containing a latex in combination with another dispersion, such as a pigment slurry, constitute a particular problem from a stability point of view. As discussed above in Section 2, the physically adsorbed latex surfactant may have a higher affinity for the pigment than for the latex, a situation which often leads to latex instability. The surfactants used as pigment... 

As mentioned above, AFM is an excellent method to evaluate the influence of the latex surfactant on the film topography. A smooth film with as little as possible of hills and craters is needed in order to obtain high gloss. Figures 6.6 and 6.7 illustrate the difference in topography, as seen during the film formation process,...
