摘　　要：对合成AM/AHAC二元共聚物的引发体系进行了筛选,研究发现,用K2S2O8-DMAAM引发体系合成的聚合物相对分子量高于其它引发体系,并在此基础上进一步考察了DMAAM浓度、单体浓度、反应温度及反应时间对聚合物分子量的影响。结果表明,单体浓度为20%、K2S2O8浓度为80 mg/L,DMAAM浓度为60 mg/L,反应温度为30℃,反应时间为6 h条件下,合成的聚合物分子量较高。Firstly, the effects of different kinds of initiating systems on relative molecular weight of the （AM/AHAC） copolymers have been investigated. The results show that the （AM/AHAC） copolymer＇s relative molecular weight was highest with K2S2O8-DMAAM as the initiating system. And then we investigate the effects of the other factors, such as DMAAM concentration, monomer concentration, polymerization temperature and time on the copolymer＇ s relative molecular weight. The results show that the （ AM/ AHAC） copolymer＇s relative molecular weight is the highest,when concentration of K2S2O8 is 80 mg/L, concentration of DMAAM is 60 mg/L, monomer concentration is 20% , polymerization temperature is 30℃ and polymerization time is 6 h.
