    Abstract: Blended fluoropolymer compositions are provided. In one embodiment, a liquid dispersion of a first fluoropolymer is blended with a liquid dispersion of a second fluoropolymer. The first fluoropolymer may be polytetrafluoroethylene (PTFE), such as a low molecular weight PTFE (LPTFE) that has been polymerized via a dispersion or emulsion polymerization process, and which has not been agglomerated, irradiated, or thermally degraded. The LPTFE may be in the form of an aqueous dispersion, having a mean particle size of less than 1.0 microns (μm), with the LPTFE having a first melt temperature (Tm) of 332° C. or less. The second fluoropolymer may be a melt processible fluoropolymer (MPF), such as methylfluoroalkoxy (MFA), fluorinated ethylene propylene (FEP), or perfluoroalkoxy (PFA), for example, in the form of an aqueous dispersion, and having a mean particle size of less than 1.0 microns (μm). Blending of the dispersions facilitates interaction of the LPTFE and MPF on a submicron level to facilitate intimate blending such that, when the blended fluoropolymer composition is dried, a crystal structure representing a true alloy of the fluoropolymers is formed, having melt characteristics that differ from those of the individual fluoropolymers. The blended fluoropolymer composition may be used to provide a coating having improved impermeability, stain resistance, abrasion resistance, smoothness, and higher contact angles.

    Abstract: A process is provided to produce an aqueous dispersion wherein the aqueous dispersion enhances the water and oil repellency of materials. The process comprises: 1) contacting at least one fluoroalkyl monomer, at least one water-dispersible polyester, water, and optionally an ethylenically unsaturated monomer to form a pre-emulsion; and 2) polymerizing the pre-emulsion in a polymerization zone in the presence of an initiator to produce the aqueous dispersion.In another embodiment, a process to produce an aqueous dispersion is provided. The process comprises: 1) contacting at least one fluoroalkyl monomer, at least one water-dispersible polyester, water, and optionally an ethylenically unsaturated monomer to form a pre-emulsion; 2) shearing the pre-emulsion to produce a mini-emulsion; and 3) polymerizing the miniemulsion in a polymerization zone to produce the aqueous dispersion.
