Abstract: A copolymer having tetrafluoroethylene units, hexafluoropropylene units, and units independently represented by formula in a range from 0.001 to 2 mole percent, based on the total amount of the copolymer. In these units, a is 0 or 1, each b is independently from 1 to 4, c is 0 to 4, d is 0 or 1, and e is 1 to 6. In the —SO2X groups, X is independently —F, —NH2, —OH, or —OZ, wherein Z is independently a metallic cation or a quaternary ammonium cation. The copolymer has a melt flow index in a range from 20 grams per 10 minutes to 40 grams per 10 minutes. The copolymer can be extruded to make articles, such as insulated cables. A method of making the copolymer is also disclosed.

Abstract: A copolymer having tetrafluoroethylene units and units independently represented by formula (I) in a range from 0.02 to 2 mole percent, based on the total amount of the copolymer. Rf is a linear or branched perfluoroalkyl group having from 1 to 8 carbon atoms and optionally interrupted by one or more —0— groups, n is independently from 1 to 6, and z is 0, 1, or 2. The copolymer has a melt flow index in a range from 20 grams per 10 minutes to 40 grams per 10 minutes. The copolymer can be extruded to make articles, such as insulated cables. A method of making the copolymer is also disclosed.

Abstract: Described herein is a composition comprising a fluorothermoplastic polymer, wherein the fluorothermoplastic polymer is derived from: (a) 60-85 mol % tetrafluoroethene; (b) 2-12 mol % hexafluoropropene; (c) 10-30 mol % vinylidene fluoride; (d) 0.2 to 5 mol % of a bromine-containing monomer. Such compositions can be used in multilayer constructions in, for example, fuel hose applications.
