The application of quaternary ammonium functionalized polymers to voltammetric analysis is described. A glassy carbon electrode coated with a thin film of poly(trihexylvinylbenzylammonium chloride) exhibited attractive permselectivity to uric acid. Typically, this polymer‐modified electrode yielded a linear voltammetric response to uric acid in the concentration range of 1–10 μM. The ion exchange properties of poly(trihexylvinylbenzylammonium chloride) was related to the Gibbs‐Donnan equation. Also, chronoamperometry was used to probe the charge‐transport and response mechanisms within this type of ionic polymer film.
