【Abstract】 New developments of two kinds of fluoropolymers modified by acrylate used in coatings are reviewed. one is thecopolymer of fluorinated-acrylate and non-fluorin monomer, in which the reactive ability of different monomers and their influ-ence on products are analyzed. The other is the copolymers modified by acrylate monomers, which are of core-shell structure andproduced by seed-polymerization. It is pointed out that the futare development should focus on improving the stain resistance ofcoatings, seeking out a method to predict the service life of the coatings in an early period of time and searching the relationshipbetween the latex structure and monomers ratio.更多还原
