Zusammenfassung:	Tetrafluoroethylene (TFE) thermoprocessable copolymers comprising: (A) from 0.1 to 15% by moles of a fluorodioxol of formula: wherein RF is a perfluoroalkyl having from 1 to 5 carbon atoms; X1 and X2, equal to or different from each other, are -F or -CF3; Z is selected from -F, -H, -Cl. (B) from 0 to 12% by moles of a perfluorinated monomer selected from hexafluoropropene (HFP) and perfluoropropylvinylether (PPVE), or their mixtures; (C) TFE forming the remaining part to 100%; with the proviso that the total amount of the monomers (A) and (B) is lower than or equal to 20% by moles.
