The functional groups are typically selected from nitrile, halogen, sulfur oxide, perfluorinated alkyl ether, and carbonyl. The core shell fluoropolymer typically comprises at least 80, 85, 90, 95, 96, 97, 98, 99 wt.% or greater of polymerized units of tetrafluoroethylene. In some embodiments, the core shell fluoropolymer further comprises up to 20 or 25 wt.% of polymerized units of other comonomers, such as hexafluoropropylene (HFP). Also described are methods of making a coated substrate, coated substrates, and core shell fluoropolymers.

Abstract: A method of making a fluoropolymer coating composition is described comprising blending a latex comprising crystalline submicron fluoropolymer particles with a latex comprising amorphous fluoropolymer particles. The method further comprises coagulating and drying the blended latexes and dissolving the dried blended latexes in a fluorinated solvent. Also described is a fluoropolymer (e.g. coating) composition comprising crystalline submicron fluoropolymer particles dispersed in a solution of fluorinated solvent and amorphous fluoropolymer; the fluoropolymer composition after removal of the solvent; and a substrate comprising a coated surface of the fluoropolymer composition. In each of these embodiments, he amorphous fluoropolymer comprises at least 90 wt-% of polymerized units derived from perfluorinated monomers selected from tetrafluoroethene (TFE) and one or more unsaturated perfluorinated alkyl ethers.
