Abstract: Fluoroacrylate copolymer stable emulsion was made by emulsion polymerization under empolyment fluorocarbon surfactant with fluoroacrylate,lauryl methylacrylate,methyl methylacrylate as monomers.The composition of copolymer was demonstrated by FT\IR,The influence of emulsifers and comonomers on latex properties were studied,and the water\resistant and oil\resistant properties of copolymer film were investigated by contact angles method.
