The effects of calcium stearate（CS),sodium dodecyl benzene sulfonate（SDBS）and the ratio of white spirit to gasoline on the stability and particle sizes of poly（acrylamide（AM）-methacryloxyethyltrimethylammonium chloride（MATMAC）prepared by reverse suspension poly merization were studied. The particle size is controlled by the aggregative growth of dispersing droplet which is affected by the dosages of CS and SDBS and the viscosity of the suspending medium.
