Photophysical and solution properties of pyrene‐labeled poly(3‐dimethyl(methylmethacryloyl ethyl) ammonium propane sulfonate), poly(DMAPS/Py), were studied in terms of fluorescence emission measurement. The I E /I M was shown as a function of polymer concentration in deionized water. I E /I M value decreases with an increase in the salt concentration. The addition of surfactants to the aqueous solution of poly(DMAPS/Py) can either induce the mixed micelle of intra‐polymer and its surrounding surfactants and/or mixed micelle of inter‐polymers and their surrounding surfactants. Models of interactions between poly(DMAPS/Py) and surfactant or divalent salt in aqueous solution are proposed.
