Dissociation of a proton-conducting polyelectrolyte is studied.
Poly(2-acrylamido-2-methyl-1-propanesulfonic acid) and its monomer are investigated.
pH measurements and potentiometric titration of poly(acid) and monomer are made.
Degree of dissociation in water and NaCl solution are 0.38 and 0.74 respectively.
Dissociation of a strong poly(acid) in water is electrostatically controlled.
