The phase behaviors of the as-prepared poly(3-dimethyl(methacryloyloxy-ethyl)ammonium propane sulfonate betaine (polySBMA) solutions at high concentrations were investigated. The solution exhibited stably reversible phase transition between transparency and opacity. The transition temperature decreased with the increase of the polymer concentrations. The polySBMA had a high equilibrium concentration, which results in the as-prepared polySBMA solution with a high concentration presented an over-swelling behavior that played an important role in the transition temperature of the solution.
