摘　　要：以过硫酸铵为引发剂,N-羟甲基丙烯酰胺为助引发剂,在近似常温下采用水溶液聚合法制备了超高相对分子质量的聚丙烯酰胺。考察了引发剂用量、助引发剂用量、单体浓度、反应温度等因素对产物的影响。确定了最佳合成条件:过硫酸铵用量0.13%,N-羟甲基丙烯酰胺用量0.58%,丙烯酰胺用量6%,反应温度30℃。Using ammonium peroxysulfate as initiator and N - hydroxymethyl acrylamide as promoter, an ultra - high molecular weight polyacrylamide was prepared by aqueous solution polymerization at room temperature. The effects of initiator amount, promoter amount, monomer amount, reaction temperature on the product were investigated. The optimal synthesis condition was as follows： ammonium peroxysulfate 0.13%, N -hydroxymethyl acrylamide 0.58%, acrylamide monomer 6%, and reaction temperature 30 ℃.
