摘　　要：合成了丙烯酰乙二胺盐酸盐及其聚合物聚丙烯酰乙二胺盐酸盐,并通过红外光谱(FT-IR)和核磁共振(1H-NMR)对单体及聚合物进行了结构表征,考察了温度对聚丙烯酰乙二胺盐酸盐水溶液的特性黏数和pH值的影响。实验结果表明,在20℃～60℃的范围内聚丙烯酰乙二胺盐酸盐溶液的特性黏数符合Fouss经验式。当温度从20℃升至60℃时,特性黏数从28.49dL/g降低至15.77dL/g。温度从30℃升至55℃时,聚丙烯酰乙二胺盐酸盐溶液的pH降低了0.35。N-acryloyl-1,2-diaminoethane hydrochloride and the resulting polymer were obtained,and chemical structures of the monomer and poly（N-acryloyl-1,2-diaminoethane hydrochloride） were characterized and confirmed by Fourier transform infrared spectrum（FT-IR） and 1H nuclear magnetic resonance spectrum（1H-NMR）.Intrinsic viscosity and pH of the polymer aqueous solution were investigated at different temperature.The experimental results show intrinsic viscosity is in accordance with Fuoss empirical formula and decreases from 28.49 dL/g to 15.77 dL/g when the temperature of solution increases from 20 ℃ to 60 ℃.In addition,pH values of the polymer aqueous solution reduce 0.35 when the temperature increases from 30 ℃ to 55 ℃.
