摘　　要：以丙烯酰胺为原料,以过硫酸铵为引发剂,采用水溶液聚合法制备聚丙烯酰胺。探讨了单体质量分数、引发剂用量、反应时间、反应温度等对聚合物相对分子质量的影响;并借助于正交试验分析,初步得出PAM相对分子质量与合成条件的关系。Nonionic polyacrylamide（ PAM ） was synthesized with acrylamide using （NH4）2 S2 O8 as initiator by the method of copolymerization in aqueous solution. Effects of monomer concentration, dosage of initiating agent, reaction temperature and reaction time on relative molecular mass of the synthetic nonionic polyacrylamide were analysed. Moreover, the relationship between relative molecular mass of PAM and synthesis conditions was obtained by orthogonal experiment.
