aqueous medium containing a particulate suspension of inorganic particles to form a discontinuous oil droplets phase in a continuous water phase the mixture is subjected to shearing forces by agitation homogenization and the like to reduce the size of the droplets after shearing is stopped an equilibrium is reached with respect to the size of the droplets as a result of the stabilizing action of the inorganic particulate stabilizer in coating the surface of the droplets and then polymerization is completed to form an aqueous suspension of polymeric particles in an aqueous phase having a uniform layer thereon of inorganic particles this process is described in u s pat nos 2 932 629 and 4 148 741 incorporated herein by reference in the u201c polymer suspension u201d technique a suitable polymer is dissolved in a solvent and this solution is dispersed as fine water immiscible liquid droplets in an aqueous solution that contains inorganic particles as a stabilizer equilibrium is reached and the size of the droplets is stabilized by the action of the inorganic particles coating the surface of the droplets the solvent is removed from the droplets by evaporation or other suitable technique resulting in polymeric particles having a uniform coating thereon of inorganic particles this.
