| Abstract: | A rapid and effective starch grafted acrylamide superabsorbent was synthesized by grafting a crylamide onto potato starch,using N,N-methylenebisacrylamide as a crosslinking agent and pota-ssium persulfate and sodium sulfite as a redox initial system.In order to get the best condition,eight factors were investigated,such as temperature,initiator concentration,the monomer concentratio,etc.The optimum result of the orthogonal experiments is that the superabsorbent can absorb 58.5 times 1%sodium chloride soluti... |
