  • THERMALLY STABLE FLUOROPOLYMERS
    Publication number: 20100022702
    Abstract: A fluorinated polymer composition, an article made with the fluorinated polymer composition and a method of making the fluorinated polymer are provided. The method comprises a partially fluorinated polymer which has carboxylic or carboxylate end groups and forming a potassium salt with the end groups of the fluorinated polymer through ion exchange. The resulting partially fluorinated polymers demonstrate high thermal stability without the addition of thermal stabilizers.
