  • Polymer processing additive containing a perfluorovinylether-modified flouropolymer and a melt processable thermoplastic polymer composition employing the same
    Patent number: 6380313
    Abstract: A polymer processing aid composition, a melt processable polymer composition that uses the polymer processing aid, and a method of improving the melt processability of a thermoplastic polymer are provided. The polymer processing aid composition comprises a fluoropolymer that comprises interpolymerized units derived from a perfluorovinyl ether, preferably one having the formula CF2═CF—(OCF2CF(CF3))AORf where a has a value of 0 to 3 and Rf is a perfluoroaliphatic (preferably perfluoroalkyl or perfluoroalkoxy) having from 1 to 8 (preferably 1 to 3) carbon atoms.

    Inventors: Maria P. Dillon, Harald Kaspar, Bernhard Hirsch, Klaus Hintzer, Karl-Dieter Weilandt
  • Polymer processing additive containing a multimodal fluoropolymer and melt processable thermoplastic polymer composition employing the same
    Patent number: 6277919
    Abstract: A polymer processing aid composition, a melt processable polymer composition that uses the polymer processing aid, and a method of improving the melt processability of a thermoplastic polymer are provided. The polymer processing aid composition comprises a multimodal fluoropolymer that preferably comprises interpolymerized units derived from an ethylenically unsaturated fluoromonomer tetrafluoroethylene and at least one ethylenically copolymerizable alpha-olefin monomer.

  • Fluoroplastic polymers with improved characteristics
    Patent number: 6242548
    Abstract: A multimodal fluoroplastic terpolymer composition is provided. The terpolymer can be extruded at high extrusion speeds without having to reduce its molecular weight. The terpolymer is useful by itself; in combination with conductive fillers to provide an electrostatically dissipative composition; and as a polymer processing aid. The polymer has a low molecular weight component, a high molecular weight component and, optionally an ultra-high molecular weight component.
