摘要：

Acrylamide, AM, was polymerized radically at 50 degree C with different concentrations of monomer and 4,4 prime -azobis-4-cyanovaleric acid, ACV, to high conversions. The polyacrylamides were isolated by precipitation into ethanol. After drying, the limiting viscosity numbers and apparent molecular weights of these polyacrylamides were determined viscometrically in distilled water and 1 M sodium chloride solution. The dependence of limiting viscosity numbers on percentage conversion is discussed, and the significance of polymer branching is assessed.
