| Abstract: | The instability of viscosity of polyacrylamide(PAM) aqueous salt solutions which are used in the viscometric method for the determination of the molecular weight of PAM,PAM 1 mol/L NaNO3, PAM-0. 1 mol/L Na2SO4, and PAM-0. 5 mol/L NaCl, was examined. Some stabilizers were added in the solutions, and the dependence of viscosity on time was studied in order to find stable systems to determine the molecular weight of PAM. |
