Solution polymerization of acrylamide to high conversion

The solution polymerization of acrylamide initiated by 4,4′-azobis-4-cyanovaleric acid (ACV) at high monomer concentrations in the temperature range 25–50°C has been studied. Molecular weight distributions were measured by gel permeation chromatography and by electron microscopy. Molecular weight measurements show that transfer to monomer plays a dominant role in controlling the molecular weight averages.
