The Synthesis of Starch-acrylamide Graft Copolymer by UV Polymerization and Its Flocculation Effect
XU Chu-yang · Mining and Metallurgical Engineering · 2005
Starch-acrylamide graft copolymer (St-PAM) was synthesized by means of UV (ultraviolet) polymerization. Experiment research was undertaken on the factors influencing the UV polymerization, as well as on the best technical conditions for it. And meanwhile the copolymerization and its flocculation effect have also been checked in experiments. Results show that not only it is feasible for starch-acrylamide graft copolymer to be synthesized with such UV polymerization method, but also the obtained starch-acrylamide graft copolymer has an equivalent or even better flocculation effect than PAM when it is used as flocculent.
