摘　　要：Fluoropolymer-modified ployacrylate emulsion was prepared by the copolymerization of methyl methacrylate(MMA), butyl acrylate(BA) and styrene(St) in the presence of swollen particles of PTFE. Compared with acrylate emulsion, the fluoropolymer-modified polyacrylate emulsion exhibits obvious improvements on the quality of the emulsion and latex film. The surface tension and viscosity of the emulsion are 33 mN/m and 1.7 mPa·s, respectively. The minimum film formation temperature(MFT) is 4 ℃. The film survived 3 000 cycles of water rinse, and the adhesion force is grade one.Fluoropolymer-modified ployacrylate emulsion was prepared by the copolymerization of methyl methacrylate(MMA), butyl acrylate(BA) and styrene(St) in the presence of swollen particles of PTFE.
