Vinylphosphonic acid was polymerized at 80 ºC by free radical polymerization to give a high molecular weight polymer (Mw of 6.2 x 104) as determined by static light scattering. Titration curves indicated that high molecular weight poly(vinylphosphonic acid) PVPA behaved as a monoprotic acid. These results were compared with the titration behavior of poly(acrylic acid) and poly(vinylsulfonic acid), which were already documented in the literature.
