    摘要: Disclosed is an aqueous polymerization process for the manufacture of a fluoropolymer comprising repeating units arising from a perfluoromonomer and a monomer having a functional group and a polymerizable carbon-carbon double bond, comprising: (A) combining water and a perfluoromonomer to form a reaction mixture; (B) initiating polymerization of the perfluoromonomer; (C) polymerizing a portion of the perfluoromonomer to form particles of polymerized perfluoromonomer in the reaction mixture; (D) adding to the reaction mixture a monomer having a functional group and a polymerizable carbon-carbon double bond; and (E) polymerizing the perfluoromonomer and the monomer having a functional group and a polymerizable carbon-carbon double bond in the presence of the particles of polymerized perfluoromonomer to form the fluoropolymer. The fluoropolymer is useful as an adhesive and coating.

    摘要: A melt-mixed composition of non-melt flowable polytetrafluoroethylene (PTFE) and melt-fabricable perfluoropolymer is provided that exhibits thixotropy at increasing shear rate in the molten state and high elongation at break even at PTFE concentrations well above 4 wt %, based on the combined weight of the PTFE and the perfluoropolymer, e.g. at least 200% up to at least 30 wt % PTFE, the composition also exhibiting the structure of a dispersion of submicrometer-size particles of the PTFE in a continuous phase of the melt-fabricable perfluoropolymer.
