ABSTRACT:
Particulate amorphous silica, surfactant, monomer, and an aqueous solvent are brought into mutual contact so that as equilibrium is approached the concentration of the surfactant in the liquid phase is below, at, or slightly above the critical micelle concentration; the monomer is then polymerized to form polymeric film associated with at least a portion of the surface of the particulate amorphous silica, the polymeric film being (i) homopolymer of an aliphatic monomer or (ii) copolymer of at least two different monomers.
