摘要
用自制的引发剂通过溶液聚合反应制备了淀粉、丙烯酰胺(AM)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)三元共聚物,并以此为原料进行Mannich反应,制备出叔胺-磺酸型淀粉基高分子聚合物,并得到了最佳反应条件。通过红外光谱仪和核磁共振波谱仪对其进行了表征。产物对印染和造纸污水的固体悬浮物和COD去除率优于聚丙烯酰胺(PAM)。
The amphoteric copolymer was synthesized with self-made initiator, starch, acrylamide and 2-acrylamino-2- methylpropanesulfonate by aqueous solution polymerization and Mannich reaction, The product was characterized by IR, ^1H-NMR, The optimum reaction conditions were obtained. The suspended substance and COD removal ratio of the polymer for dyeing factories＇ and paper mill wastewater is better than that of polyacrylamide.
