Investigation of the degradation and stability of acrylamide-based polymers in acid solution: Functional monomer modified polyacrylamide
They discovered that the viscosity of hydrolyzed polyacrylamide exhibits pH dependence as characterized by transition zones (at pH = 3 and pH = 6), where the viscosity suddenly changes. This is because the hydrogen ions adsorb and dissociate
