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.

Abstract: A method of making a copolymer is disclosed. The method includes copolymerizing components including tetrafluoroethylene and a compound represented by formula CF2═CF—O—(CF2)a—SO2—X, wherein “a” is a number from 1 to 4, and X is —NZH, —NZ—SO2—(CF2)1-6—SO2X′, or —OZ, wherein Z is independently a hydrogen, an alkali metal cation, or a quaternary ammonium cation, and wherein X is independently —NZH or —OZ. The components include at least 60 mole % of tetrafluoroethylene based on the total amount of components. A copolymer prepared by the method is also provided. A method of making a membrane using the copolymer is also provided. The present disclosure also provides a polymer electrolyte membrane that includes a copolymer made by the method and a membrane electrode assembly that includes such a polymer electrolyte membrane.

Abstract: A method of making a highly fluorinated polymers and resulting aqueous mixtures. The method comprising polymerizing one or more perfluorinated monomers in an aqueous emulsion polymerization in the presence of a polymerizable fluorinated emulsifier to form a perfluorinated polymer. The polymerizable fluorinated emulsifier has the formula X2C═CX(CF2)m(CH2)n[O—(CX2)p]q—[O—(CX2)r]s−[O—(CX2—CX2)]t—[(O)w—(CX2)u]v—[CH2]z—Y. The method also provides for isolating the highly fluorinated polymer and post-fluorinating the isolated highly fluorinated polymer.

Abstract: A copolymer having tetrafluoroethylene units, hexafluoropropylene units, and units independently represented by formula 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 —O— groups, z is 1 or 2, each n is independently from 1 to 6, and m is 0 or 1. The copolymer has a melt flow index in a range from 25 grams per 10 minutes to 35 grams per 10 minutes and has a combined number of unstable end groups and —CF2H end groups in a range from 25 per 106 carbon atoms up to 120 per 106 carbon atoms. The copolymer can be extruded to make articles, such as insulated cables. A method of making the copolymer is also disclosed.
