    摘要: The present invention relates to a method for the polymerization in an aqueous medium of monomers, and especially of fluoromonomers, using non-fluorinated surfactants; and the fluoropolymers formed therefrom. Specifically, the method of the polymerization uses one or more non-fluorinated surfactants selected from the group consisting of polyvinylphosphonic acid, polyacrylic acids, polyvinyl sulfonic acid, and salts thereof. Additionally, the use of polyvinylphosphonic acid, polyacrylic acids, polyvinyl sulfonic acid as surfactants in aqueous free radical polymerization is also novel.

    摘要: The invention relates to aqueous fluoropolymer hybrid compositions made by a seeded emulsion polymerization process, having improved film formation properties. The seed is a fluoropolymer dispersion. At least two different monomer compositions are added sequentially to the seeded dispersion. These monomer compositions preferably include acrylic monomers. The first monomer composition is selected for miscibility with the fluoropolymer dispersion. The second monomer composition is selected to have a glass transition temperature (Tg) of less than 30° C. The final composition can be formulated to make coatings with a minimum film forming temperature (MFFT) of less than 5° C., and a maximum VOC of 50 g/liter. The composition is especially useful for coatings and films.
