(Uyaver, S.; Seidel, C. Macromolecules 2009, 42, (4), 1352-1361.) When the dissociation does not depend on the pH, the polyelectrolyte is called ¡°strong¡±polyelectrolyte. (Gromer, A.; Rawiso, M.; Maaloum, M. Langmuir 2008, 24, 8950-8953.) With respect to different dissociation behaviors, one can distinguish between strong and weak PELs, a classification widely used in the chemistry community or between quenched and annealed PELs, the common classification in the physics community. Strong polyelectrolytes, poly-salts as, e.g., Na-PSS, dissociate completely in the total pH range accessible by experiment. (Uyaver, S.; Seidel, C. J. Phys. Chem. B 2004, 108, (49), 18804-18814.) |
