ActiveDetermination for molecular weight of polyacrylamide by viscometry
聚丙烯酰胺分子量测定 粘度法
Application Summary AI generated
This standard specifies the viscometric method for determining the molecular weight of polyacrylamide, a polymer widely used as a flocculant in water treatment and as a thickener in enhanced oil recovery. It is applied in quality control laboratories within the chemical and plastics industries to characterize the polymer's chain length, which directly affects its performance in these applications. The method relies on measuring the intrinsic viscosity of dilute polymer solutions in a controlled solvent environment.
