摘要：

Polyacrylamide and its copolymers of acrylic acid have wide application as flocculants and mobility control fluids in enhanced oil recovery. Detailed knowledge of the molecular weight and molecular weight distribution has not been available for these polymers because their exceptionally high molecular weight exceeds the capabilities of traditional techniques, such as size exclusion chromatography (SEC). The combination of hydrodynamic chromatography (HDC) and low-angle laser light scattering (LALLS) detection can be used to measure the molecular weight distribution of this group of polymers.
