Technical Abstract: Graft copolymers of starch and polyacrylamide have been prepared using a twin screw extruder. The effects of monomer/starch ratio and moisture content on conversion, graft efficiency, graft molecular weight, and frequency of grafting are discussed. Converion of monomer to polymer exceeding 90% and grafting efficiencies exceeding 60% can be achieved by this process, with residence times of approximately 250 seconds or less.
