Abstract
The present invention provides a method of preparing an organosol of inorganic particles, comprising mixing an aqueous dispersion or sol of inorganic particles with an organic liquid and a polymer or oligomer having functionality that adsorbs onto the inorganic particles; and allowing the mixture to separate into an aqueous layer and an organic layer, the organic layer comprising the inorganic particles. The invention also provides a polymer composition or coating composition made by this method. A coating composition is applied to a substrate and cured to provide a coating layer on the substrate. A polymer composition containing the inorganic particles is molded into an article.
