【Abstract】 The polymer- polyol- dispersions have been synthesized by using free radical copoly- merization of the macromers and styrene/acrylonitrile.The conversion rate of St/AN under various reaction conditions and the radius of particles in the dispersion were measured.It has been found that polymerization kinetics is similar to dispersion polymerization in small molecule media.The conversion rate of St/AN is affected by the additions of macromers and the stir rate and the reaction temperature.更多还原
