  • Degradation on polyacrylamides. Part I. Linear

    2003-3-1 · Hydrolysis of polyacrylamide. Therefore, when the PAAms were heated at 95 °C, hydrolysis of the side chain amides to acid groups occurred. This was evidenced by the change in pH of the solution, by the titration of the acid groups with base, and by NMR spectroscopy, which clearly showed a second carbonyl peak with the same chemical shift as that of an authentic PAA.
