Aqueous fluoropolymer dispersions |
摘要 |
A stable, aqueous fluorocopolymer dispersion prepared by aqueous dispersion polymerization of a) a dispersed phase containing a fluoroolefin monomer component and a vinyl ether monomer component in the presence of b) a base neutralized, stable aqueous dispersion of a polymeric dispersant having an acid value of at least 1.5 mg KOH/gram not exceeding about 35 mg KOH/gram and the amount of neutralizing base does not exceed about 10 percent based on resin solids of the dispersant. The acid value is adapted to provide a stable dispersion of the fluorocopolymer in water without externally added surfactant. Thermoplastic and thermosetting coating compositions can be prepared from these aqueous fluorocopolymer dispersions.
