摘　　要：采用丙烯酰胺溶液聚合反应制备了相对分子质量〉2000万的高分子质量聚丙烯酰胺。探讨了聚合工艺条件对聚合物相对分子质量的影响，确立了聚合反应最佳工艺条件。最佳工艺条件为，引发剂质量分数5 ×10^-5％；单体质量分数25％；引发温度：10～15℃；聚合体系适宜的pH范围7～8。high molecular cationic polyacrylamide with molecular weight more than 2.0 million was prepared by poly- merization of propenamide. Effect of polymerization technological conditions on polymer molecular were discussed. Optimum technology of polymerization was obtained. Optimum technological conditions ： mass fraction of initiating agent is 5 ×10^5 %, mass fraction of monomer is 25 %, trigger temperature is at 10 - 15 ℃, range of pH that polymerization system appropriate is at7 -8.
