Stable fluoroacrylate copolymer P(FA-BA-MMA) was successfully synthesized by miniemulsion polymerization under microwave irradiation.Conversion of the monomers was determined by gravimetry.The water resistance of the latex films was investigated and the stability of the miniemulsion was observed.The surface properties of the copolymer films were investigated by contact angle measurement.The results show that the miniemulsion copolymerization under microwave irradiation had higher reaction rate and higher conversion than traditional heating,and the centrifugal stability was better.The monomerconversion under microwave irradiation was 80% at 10 min.The water absorption ratio and surface free energy of the fluorinated acrylate films both decreased evidently compared with that of the acrylate copolymer films without fluorine.The water absorption ratio and the surface energy could reach 1.43% and 14.85 mJ/m2 respectively when the amount of FA used in the copolymerization was 25%.
