摘　　要：采用水溶液聚合法制备了超高分子量聚丙烯酰胺/丙烯酸盐/疏水缔合单体共聚产品。考查了体系中不同疏水缔合单体浓度、不同起始反应温度、不同引发剂用量和不同pH对疏水缔合产品分子量以及对高浓度洗煤水中悬浮物(SS)和化学需氧量(COD)处理效果的影响,从而得到制备疏水缔合聚丙烯酰胺产品的最优反应条件。The copolymerization product of ultra-high molecular weight polyacrylamide/acrylate/hydrophobic association monomer was prepared by aqueous solution polymerization.The effects of different hydrophobic association monomer concentration,different initial reaction temperature,different initiator dosage and different pH on the molecular weight of hydrophobic association products and the treatment effect of suspended solids(SS)and chemical oxygen demand(COD)in high concentration coal washing water were investigated,so as to obtain the optimal reaction conditions for preparing hydrophobic association polyacrylamide products.
