Abstract: The invention relates to novel linear, semi-crystalline, functional fluoropolymers that have been obtained by copolymerizing a fluorinated vinylic monomer and a hydrophilic monomer chosen from vinyl alkyl acids, vinyl phosphonates, functional acrylamides, carbonates, vinyl ethers, alkoxy compounds, and double hydrophilic group monomers.

Abstract: The present invention pertains to a non-linear, copolymer comprising recurring units derived from vinylidene fluoride (VDF) monomer, at least one functional comonomer and optionally at least one fluorinated ethylenic comonomer. The non-linear fluorinated copolymer comprises from 0.01 to 3.0% by moles of recurring units derived from functional comonomer. The non-linear fluorinated copolymer can be used as electrode binder in batteries.

Abstract: The invention relates to sized reinforcing fibers that comprise a reinforcing fiber sized with a fluoropolymer. The fluoropolymer is functionalized and/or the reinforcing fiber is sized with a compatible functional non-fluorinated polymer that is compatible with the fluoropolymer. Functionalization of the fluoropolymer or the compatible non-fluorinated polymer provides enhanced properties, such as increased adhesion to the reinforcing fiber.

Abstract: The invention relates to fluoropolymer composites having a fluoropolymer matrix containing a functionalized fluoropolymer composition, and reinforced with fibers. The fibers can be chopped fibers, long fibers, or a mixture thereof, and the fluoropolymer matrix preferably is based on polyvinylidene fluoride. Any type of fibers, sized or unsized may be used with the functionalized fluoropolymer matrix composition to form the fluoropolymer composite.

Abstract: The invention relates to very high melt flow fluoropolymer compositions, having low melt viscosities. The fluoropolymers have low molecular weights of from 5 kDa to 200 kDa and melt viscosities of less than 2 kilopoise (kP) at 232° C. and 100 s−1. One use for the high melt flow fluoropolymers is in the formation of very small diameters fibers, useful for melt-blown non-woven materials. Fiber diameters of less than 9 microns, and preferably 500 to 2000 nm can be produced.
