Abstract
The present invention relates to a method of preparing polymer compositions comprising modified metal oxides in a polymer wherein a nanoparticle dispersion of a metal oxide in a non-aqueous solvent is combined with at least one coupling agent to form a nanoparticle dispersion of a modified metal oxide in the non-aqueous solvent. The nanoparticle dispersion is then combined with a polymer followed by the removal of the non-aqueous solvent or, alternatively, combined with a monomer, which is polymerized to form the polymer and removal of the solvent, in any order. Also disclosed are polymer compositions prepared by this method.
