| 摘 要： | INTRODUCTIONStarch is a kind of abound and cheap resource, which can regenerate and whose structure is composed of glucose units that contain many active hydroxyl groups. The modified starch can be synthesized with various chemistry, physics and biology methods. It has extensive uses among all kinds of paper chemical products. The graft copolymerization of starch with acrylamide(AM) and cationic monomer can join the synthetic chain with high molecular onto the starch backbone. This is a …

| Abstract: | The cationic graft copolymer was synthesized by reversed phase emulsion copolymerization of starch with diallydimethyl ammoniumlchlorid (DADMAC) and acrylamide(AM). The copolymerization was carried out using (NH4)2S2O8-NH2CONH2 redox as initiator and selecting Span-20 as emulsifier. The effects of emulsifier content in oil phase, volume ratio of oil to water, initiator concentration and mole ratio of DADMAC to AM on the graft copolymerization were discussed. The optimum condition of synthetics was found with the orthogonal test method. |
