Abstract

A fluoropolymer contains (in wt.%) tetrafluoroethylene (60-99.99), hexafluoropropylene (0-30), olefinic fluorinated or non-fluorinated monomer (0-10), perfluoro alkyl vinyl ether having 1-5C in the alkyl radical (0-35), and perfluoro vinyl ether (0.01-35). The fluoropolymer has a melting point of >=160[deg]C. A fluoropolymer contains (in wt.%) tetrafluoroethylene (TFE) (60-99.99), hexafluoropropylene (HFP) (0-30), olefinic fluorinated or non-fluorinated monomer (0-10), perfluoro alkyl vinyl ether having 1-5C in the alkyl radical (0-35), and perfluorovinyl ether (0.01-35). The fluoropolymer has a melting point of >=160[deg]C. The perfluoro vinyl ether is a compound of formula CF2=CFO(CF2)nORf. n : 2-6; Rf1-6C perfluoroalkyl. Independent claims are also included for (A) a method of producing the fluoropolymer, (B) a method of making an extruded article comprising extruding a melted composition comprising fluoropolymer, and (C) an extruded article. The fluoropolymer is produced by copolymerizing TFE, perfluorovinyl ether, and optionally olefinic fluorinated or non-fluorinated monomer and perfluoro alkyl vinyl ether through aqueous emulsion polymerization or suspension polymerization. The perfluorovinyl ether can be of formula CF2=CF[(O(CF2)n]m(OCF2)xRf. n : 2-6; m : 1-3; x : 0-4; Rf1-6C perfluoroalkyl.
