Technical Abstract: Graft copolymers of starch with water-soluble polymers such as polyacrylamide have potential applications including hydrogels, superabsorbents, and thickening agents. Reactive extrusion is a rapid, continuous method for production of starch graft copolymers with high reaction and grafting efficiencies. A number of water-soluble or dispersible free radical initiators have been evaluated in the reactive extrusion process for efficiency and impact on grafting parameters. The results obtained with different initiators will be compared.
