Abstract
The novel fluorinated polyacrylate latex was successfully prepared by emulsion polymerization of perfluorononylene allyl ether, butyl acrylate and methyl methacrylate initiated by potassium persulfate in water and emulsified with the reactive surfactant. Films of the novel fluorinated polyacrylate latex were prepared by coating the latex directly on the clean glass sheet and allowed to dry at 80°C in the bake oven. The characteristics of the film such as hydrophobicity and glass transition temperature were studied; its structure was investigated by FTIR spectrometry and NMR. The influence of the fluorinated monomer content on the emulsion polymerization and performance of the latex were also studied. It was shown that the hydrophobicity and glass transition temperature of the latex are improved when the fluorinated monomer is introduced to copolymerize with other monomers, however, the stability of emulsion polymer and the conversion rate is decreased with the increase of its content.
