ABSTRACT:
Colloidal size particles of an inorganic solid such as magnetic iron oxide or titanium dioxide are encapsulated in a hydrophobic addition polymer such as a polymer of styrene by a polymerization process wherein a water-immiscible (hydrophobic) monomer is dispersed in an aqueous colloidal dispersion of the inorganic particles and subjected to conditions of emulsion polymerization. The resulting encapsulated particles are usefully employed as catalysts, toners, pigments and diagnostic latexes that have magnetic characteristics.
