Title:
EMULSION POLYMERIZATION METHODS INVOLVING LIGHTLY MODIFIED CLAY AND COMPOSITIONS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO2002024758
Kind Code:
A3
Abstract:
Processes for utilizing various emulsion polymerization procedures for preparing aqueous nanocomposite dispersions are disclosed. The disclosed processes include both in-situ polymerization in the presence of at least partially exfoliated, lightly modified clays as well as admixtures of polymer dispersion with at least partially exfoliated, lightly modifies 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.
