Abstract：A modified styrene-acrylic emulsion was synthesized, and the effect of the weight ratios of emulsifier, initiator, crosslinking agent and fluorine monomer on the stability and adhesion of the emulsion were evaluated. The results showed that, in a typical reaction process with following conditions: the amount of emulsifier was 0.8~1.0%; the usage of APS was 0.8%; the usage of crosslinking monomer was 3%; the usage of fluorine monomer was 16%, the obtained emulsion was stable and the adhesion on tinplate was 11.7 MPa. The properties of films prepared from the emulsion were as follow: excellent water and oil resistance with a pencil hardness of 2H, the contact angle between water droplet and the film of 118.2°. The study presents that the film has some potential applications in the oil-water separation.

Key words：modified styrene-acrylic emulsion; oil-water separation; stability; hydrophobic
