Although there are obvious advantages and benefits in generating fluorinated acrylate (FA) polymers via emulsion polymerization

their incorporation into colloidal particles is not straightforward.The current studies offer a simple synthetic approach which nucleated directly in the monomer droplets and prevented the diffusion of hydrophobic C-F monomers from monomer droplets through the aqueous phase to micelles.In this paper

the cationic copolymer emulsion based on FA

SMA

and MMA was successfully synthesized via miniemulsion polymerization.Size distribution analyzer and transmission electron microscope were used to study the particle size and morphology influenced by ultrasonic amplitude

ultrasonic time and mole ratio of costabilizer hexadecane (HD) to total surfactants

respectively.The results showed that particle size was changed in the range of 80～150 nm

and various particle morphologies were obtained

such as core-shell

snowmanlike and strawberry-like.Long fluoro chains can result in the micro-phase separate which is beneficial to improving the water and oil-repellency.The static water contact angle on the cotton treated with the cationic emulsion of 1.0 wt% solid content can nearly reach to 150°.
