AbstractPeroxide‐induced copolymerization of tetrafluoroethylene (TFE) with hexafluoropropylene (HFP) and acrylic acid (AA) at different molar ratios of monomers, reaction time, pressure, and initiator concentration was studied. By means of IR spectroscopy and temperature and phase characteristics of the copolymers obtained it was proved that a ternary copolymer of TFE, HFP, and AA was synthesized. Fluoro‐containing polymers with ion‐exchange capacities up to 0.8 meq/g were obtained. The composition of binary TFE‐HFP and ternary TFE‐HFP‐AA copolymers and some of their characteristics were determined. Copolymerization takes place mainly in the stationary state with an induction period. Polymerization rateR∼ In0.7, which is presumably connected with chain transfer r
