Factors affecting the viscosity of polyacrylamide

The viscosity of polyacrylamide solution mainly reflects the internal frictional resistance between liquid molecules due to flow or relative movement. The internal friction resistance is related to the structure of the polymer, the nature of the solvent, the concentration of the solution, temperature and pressure and other factors.
