Water-soluble random copolymer ammonium ionenes with M̄ w in the range of 17.4 to 20.8 kg mol -1 and various charge densities are synthesized from 1,12-dibromododecane, N,N,N′,N′-tetramethyl-1,6- hexanediamine, and 1,12-bis(N,N-dimethylamino)dodecane. Anion exchange of the bromine counterion forms ionenes with TFSI, TFO, and BF 4 anions. The nature of the counteranion and charge density tailor the thermal and rheological properties of 12,6/12-ionenes, respectively. X-ray scattering reveals microphase separation with a correlation length of ≈7 nm for ionenes with 50 to 90% N,N,N′,N′-tetramethyl-1,6-hexanediamine content. Ionene copolymers display polyelectrolyte behavior in methanol based on a predicted scaling relationship between specific viscosity (ν sp) and concentration.
