Processes for utilizing various emulsion polymerization procedures for
preparing aqueous nanocomposite dispersions are disclosed. The disclosed
processes include both in-situ polymerizations in the presence of at
least partially exfoliated, lightly modified clays as well as admixtures
of polymer dispersions with at least partially exfoliated, lightly
modified clay dispersions. The disclosed nanocomposite dispersions are
useful for preparing a variety of materials, such as coatings, adhesives,
caulks, sealants, plastics additives, and thermoplastic resins. Processes
for preparing polymer nanocomposite powders and use of these powders as
plastic resin and plastics additives are also disclosed.
