| 摘 要： | 本实验以淀粉、丙烯酰胺、阳离子单体(二甲基二烯丙基氯化铵)为原料,采用过硫酸铵-尿素氧化还原引发体系,以油酸失水山梨醇酯为乳化剂,通过反相乳液聚合技术,合成阳离子改性淀粉接枝共聚物.分析讨论了单体配比、乳化剂用量、引发剂用量及油水体积比等合成条件对共聚物性能的影响,并采用正交实验方法对合成条件进行了优化.

| 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. |
