US Patent:

20040242819, Dec 2, 2004

Filed:

Apr 27, 2004

Appl. No.:

10/832831

Inventors:

Thomas Earnest - Greenville DE, US
Daniel Favereau - Chambesy, CH
Niall McKee - Newark DE, US
Patricia Tooley - Vienna WV, US

International Classification:

C08F016/24

US Classification:

526/247000, 526/250000, 526/253000

Abstract:

The present invention relates to a partially-crystalline copolymer comprising tetrafluoroethylene, hexafluoropropylene in an amount corresponding to HFPI of from about 2.8 to 5.3, and preferably from about 0.2% to 3% by weight of perfluoro(alkyl vinyl ether), said copolymer being polymerized and isolated in the absence of added alkali metal salts, having a melt flow rate of within the range of about 303 g/10 min, and having no more than about 50 unstable endgroups can be extruded at high speed onto conductor over a broad polymer melt temperature range to give insulated wire of high quality.
