Silicone stabilized poly(methyl methacrylate) nonaqueous latex 2. Flocculation by degradation of the steric layer

The steric stabilization layers on silicone stabilized poly(methyl methacrylate) latexes, dispersed in heptane, were slowly degraded resulting in latex flocculation. These experiments were conducted to obtain measurements of the minimum amount of steric stabilizer chains required for colloid stability in good solvent conditions for the steric stabilizer. The silicone was degraded by equilibration chemistry with acidified montmorillonite as the …
