Abstract: Method of producing purified fluoropolymers comprising repeat units of tetrafluoroethylene and a fluoro-olefin comprising SO3- groups are described. In a first step, an unpurified aqueous dispersion of the fluoropolymer, including the counter-cations of the SO3- groups, is subjected to cation exchange. This cation-exchanged dispersion is then subjected to ultrafiltration. The resulting purified dispersions and fluoropolymers contain low levels of both cations and anions. Articles prepared from such purified fluoropolymers are also described.

Abstract: The method of making a three-dimensional article includes heating a composition comprising a polymer and hollow ceramic microspheres, extruding the composition in molten form from an extrusion head to provide at least a portion of a first layer of the three-dimensional article, and extruding at least a second layer of the composition in molten form from the extrusion head onto at least the portion of the first layer to make at least a portion of the three-dimensional article. Three-dimensional articles are also described. A composition including a polymer and hollow ceramic microspheres is also described. The composition may be a filament. The polymer is at least one of a low-surface-energy polymer or polyolefin. The composition can be useful, for example, in melt extrusion additive manufacturing, for example, fused filament fabrication.
