摘要: Copolymers of tetrafluoroethylene and perfluoro(ethyl vinyl ether) having perfluoro(ethyl vinyl ether) content of at least 3 wt % exhibit excellent toughness even at melt viscosities of no greater than 25.times.10.sup.3 Pa.s. The copolymers can advantageously be made by aqueous dispersion copolymerization of the monomers in the absence of alkaline buffer and preferably in the absence of organic solvent.

摘要: An aqueous dispersion contains melt-fabricable fluoropolymer particles and acrylic copolymer particles, said acrylic copolymers having a decomposition temperature of less than 340.degree. C., wherein the dispersion contains about 75 to about 95 wt % of fluoropolymer and about 5 to about 25 wt % of acrylic copolymer, based on combined weights of the two polymers. Coated articles comprise a substrate coated with a primer layer, optional intermediate coats, and a topcoat with at least the topcoat being formed from the aqueous dispersion.
