Abstract
The present invention relates to a composition comprising an aqueous dispersion of polymeric composite microspheres comprising an aqueous dispersion of polymeric composite microspheres that comprise a polysiloxane and a polymer, as defined herein, and a suspension polymerization process for making the composition. The composition is useful for making defect free coatings with a relatively low coefficient of friction.
