Fluorosilicone polymers have many excellent properties,such as high and low temperature resistance,weather resistance,corrosion resistance,chemical stability,water and oil resistance.Acrylate copolymer latexes containing fluorosilicone units were prepared via core-shell emulsion copolymerization of methacrylate (MMA),butyl acrylate (BA) and fluorosilcone monomer which was prepared by fluorinated alcohol and vinyltriethoxyl silane.Results show that latexes had good storage stability,and high and low temperature stability.The structure of the fluorosilcone monomer and the acrylate copolymer containing the fluorosilicone were characterized by FT-IR.The morphology of the latex particles was studied with TEM,which confirmed the core-shell structure of the particles,and the particle diameter was 125 nm or so.Compared to that of the copolymer films,the water absorption of the latex films containing fluorosilicone units reduced to 8.32%,and the thermal decomposition temperature increased by 23℃.The latex films could be dissolved in THF and toluene,and could be swollen in methanal and ethanol.
