Abstract: The influence of particle morphology of the fluorinated polyacry late soap - free emulsion prepared by a semi - continuous process and polymerization conditions on the ave rage particle size of the emulsion was studied by TEM and dynamic light scattering. The properties of emulsion and surface properties of the coating s film were measured.The latexparticles showed aspheric shape and narrow distribution.The emulsion exhibited good storage stability.The contactangle of the film w ith water is 110.2,and showedlow mo isture absorption and outstanding surface performance.
