The competitive binding of fluorescence‐tagged poly(methacrylate) polyanions and poly(phosphate) polyanions with different poly( N ‐alkyl‐4‐vinylpyridinium) polycation quenchers (alkyl = methyl, ethyl and propyl) was studied in the region 278÷333 K by fluorescence quenching technique. The equilibrium of this interpolyelectrolyte substitution reaction proved to be temperature sensitive except in the case when the poly( N ‐methyl‐4‐vinylpyridinium) polycation was used. Thermodynamic parameters of the reaction were determined. The possibility of effective temperature control of the interpolyelectrolyte reaction might be important for understanding, prediction and utilization of transformation processes of complex particles formed by electrostatically complementary (biological) macromolecules.
