Abstract: The invention relates to blends containing polymers of vinylidene fluoride, having low ductile-brittle transition temperatures and having excellent low temperature impact properties while maintaining the positive aspects of unmodified vinylidene fluoride-containing polymers. The blends of this invention are produced by adding a core-shell impact modifier (CSIM) comprised of a polysiloxane core and a shell compatible with vinylidene fluoride-containing polymer. The blends are further characterized by the presence of a heterogeneous copolymer composition comprised of two or more distinct phases and/or at least one flame and smoke suppressant. The preparation of these new blends can be done by conventional thermoplastic compounding techniques such as twin screw compounding; alternatively, the CSIM can be introduced earlier, such as in the latex. The unique properties of the new blends make them useful in end-use applications where those properties provide performance advantages, such as in wires & cables and in oil and gas applications.

Abstract: The invention relates to the use of a high performance thermoplastic polymer binder material for immobilizing adsorptive materials, such as activated carbon, in gas storage devices. The use of these binders, especially polyamide binders, polytetrafluoroethylene binders, or polyvinylidene fluoride binders such as Kyblock® resin, provides for high sorbent packing density, low fouling solid structure that maximizes the volume of gas to the volume of the storage space.

Abstract: The invention relates to a porous separation article having a fluoropolymer or polyamide binder interconnecting one or more types of interactive powdery materials or fibers. The interconnectivity is such that the binder connects the powdery materials or fibers in discrete spots rather than as a complete coating, allowing the materials or fibers to be in direct contact with, and interact with a fluid. The resulting article is a formed multicomponent, interconnected web, with porosity. The separation article is useful in water purification, as well as in the separation of dissolved or suspended materials in both aqueous and non-aqueous systems in industrial uses. The separation article can function at ambient temperature, as well as at elevated temperatures.

Abstract: This invention relates to a waterborne fluoropolymer composition useful for the fabrication of Li-Ion-Battery (LIB) electrodes. The fluoropolymer composition contains an organic carbonate compound, which is more environmentally friendly than other fugitive adhesion promoters currently used in waterborne fluoropolymer binders. An especially useful organic carbonate compound is ethylene carbonate (EC) and vinylene carbonate (VC), which are solids at room temperature, and other carbonates which are liquid at room temperature such as propylene carbonate, methyl carbonate and ethyl carbonate. The composition of the invention is low cost, environmentally friendly, safer, and has enhanced performance compared to current compositions.

Abstract: The invention relates to a separator for non-aqueous-type electrochemical device that has been coated with an aqueous fluoropolymer coating. The fluoropolymer is preferably polyvinylidene fluoride (PVDF), and more preferably a copolymer of polyvinylidene fluoride. The fluoropolymer coating provides a porous coating on porous substrate separator used in non-aqueous-type electrochemical devices, such as batteries and electric double layer capacitors. The fluoropolymer coating improves the thermal resistance and mechanical integrity, and lowers the interfacial electrical impedance of the porous separator. The fluoropolymer composition optionally contains powdery particles that are held together on the separator by the fluoropolymer binder. In one embodiment, the starting fluoropolymer dispersion is free of fluorinated surfactant. In another embodiment, one or more fugitive adhesion promoters are added.

Abstract: The invention relates to integrated electrode separators (IES), and their use in lithium ion batteries as replacements for free standing separators. The IES results from coating an electrode with a fluoropolymer aqueous-based emulsion or suspension, and drying the coating to produce a tough, porous separator layer on the electrodes. The aqueous fluoropolymer coating may optionally contain dispersed inorganic particles and other additives to improve electrode performance such as higher ionic conduction or higher temperature use. The IES provides several advantages, including a thinner, more uniform separator layer, and the elimination of a separate battery component (separator membrane) for a simpler and cost-saving manufacturing process. The aqueous separator coating can be used in combination with a solvent cast electrode as well as an aqueous cast electrode either in two separate process steps, or in a one-step process.

Abstract: The invention relates to a dry free-flowing composite of a sub-micron polymer binder particles and interactive materials, and articles formed therefrom. The polymer particles are formed from a dilute latex polymer and blended with interactive materials, then the blend is spray-dried, to form a dry blend in which less than 10% of all polymer particles are in an agglomerated form. The polymer is preferably a polyvinylidene fluoride, such as Kyblock® PVDF from Arkema. The dry blend will be used to form articles and coatings by many means, for example forming a three dimensional article by heat and pressure, it can be redispersed into an aqueous coating composition, or can be electro-coated onto a substrate.

Abstract: The invention relates to novel linear, semi-crystalline fluoropolymers containing 0.5 to 25 mole percent of at least one vinyl ester monomer unit. At least 40 mole percent of the vinyl ester monomer units are present in the copolymer as single monomer units (not diads or triads or greater) between two fluoromonomer units. The invention also relates to a process for forming the fluoromonomers/vinyl ester copolymer. The fluoropolymer of the invention may be used in applications benefiting from a functional fluoropolymers including as a binder or coating in batteries, or for use in forming hydrophilic membranes and hollow fibers.
