We report on the characterization of the conformational properties of the fully aromatic polyamides poly(2‐fluoro‐ p ‐phenylene‐2‐fluoroterephthalamide) (FPFT) in methanesulfonic acid using dynamic and static light scattering and viscosity measurements. The results are in quantitative agreement with a model of polydisperse wormlike chains for the solution conformation of FPFT. A comparison with the results obtained for the unsubstituted polymer poly( p ‐phenylenterephthalamide) (PPTA) under the same experimental conditions indicates that the introduction of halogen substituents on the aromatic rings has only a weak influence on the chain flexibility.
