文摘
- •
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.
