The results suggested that the ph value, the type of monomers, the type, concentration and surface properties of inorganic nanoparticles, the type and concentration of emulsifier have a great influence on the encapsulating emulsion polymerization and the obtained latex stability. if selecting cationic emulsifier ( ctab ), low water soluble monomers ( such as ba, st ) and hydrophobic nano - silica, the inorganic nanoparticles would be encapsulated by polymers through ultrasonic irradiation successfully under alkalescent condition
