Procedure

Solutions of the sodium salt of C8 to C16 saturated fatty acids, and of oleic acid were first prepared at about 4 percent concentration in water by neutralization of the acid with sodium hydroxide. Sodium stearate solutions were prepared directly from the solid salt. Microsuspensions were prepared to contain about 50 percent of the polymer employed in Example 3B and one percent soap by adding the amount of soap or soap solution listed in the table to 150 g of purified wet cake (about 70 percent polymer) along with the required amount of water to give 50 percent polymer solids. These were then dispersed using a Virtis Mixer (five minutes) and an Eppenbach Homogenizer (15 minutes).
