Patent number: 8674042Abstract: 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 having less than about 50 ppm alkali metal ion, having a melt flow rate of within the range of about 30±3 g/10 min, and having no more than about 50 unstable endgroups/106 carbon atoms and which can be extruded at high speed onto conductor over a broad polymer melt temperature range to give insulated wire of high quality.Type: GrantFiled: November 10, 2011Date of Patent: March 18, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Thomas Robert Earnest, Jr., Daniel A. Favereau, Niall D. McKee, Patricia A. Tooley
