Interactions between quaternized chitosan and surfactant studied by diffusion NMR and conductivity

Variation of self-diffusion coefficient (D) of sodium 1-decanesulfonate as a function of its concentration in TA solution (■) or ChCat solution (●) at 30 °C ([ChCat] = 4 g L−1 in water). Included photographs show the evolution of polymer solution (precipitation occurring) during surfactant addition.
