Abstract: The emulsion polymerisation of vinylacetate is carried out under the existence of anionic detergents (sodium dodecyl sulfate and sodium dioctyl sulfo succinate), non-ionic detergents (polyoxy ethylene dodecyl ether with various degrees of polymerisation) and cationic detergent (hexadecyl trimethyl ammonium bromide). The adsorption of detergents on and the electrophoretic mobility of the emulsion particles are measured. The -degree of adsorption per gram of polymer is found to saturate at some constant value and the mobility is also recognized to .become constant at above these concentrations of detergents. The amount of saturation is constant regardless of the concentration of detergents used or the size or the surface area of the polymer particles. These facts seem to be peculialities of a slightly water-soluble monomer such as vinylacetate. As is already reported, this is not the case with styrene.
