摘要： 以丙烯酰胺(AM)、自制的1-(2-甲基丙烯酰氧丙基)-3-癸基咪唑盐酸盐(MAPD-Cl)为原料，通过自由基共聚合，得到了咪唑型阳离子聚丙烯酰胺P(AM/MAPD)。 红外光谱表征结果证明其为目标产物。 采用单因素考察和响应面分析法相结合，对聚合工艺条件进行了优化。 优化聚合条件为：单体总质量分数25.41%，反应温度26 ℃，引发剂(NaHSO3-(NH4)2S2O4)质量分数0.03%，反应时间10 h。 所得聚合物的特性粘数可达到12.56 dL/g。

Abstract: Cationic polyacrylamide P(AM/MAPD) was prepared by the radical copolymerization of acrylamide(AM) and 1-methacryloyloxypropyl-3-decylimidazolium chloride(MAPD-Cl). The as-synthesized product was characterized by IR and proved to be the target product. Synthetic conditions were optimized with the single factor optimization coupled with the response surface methodology(RSM). Based on the results of single factor optimization, mass fraction of monomer, reaction temperature, initiator concentration, and time were obtained and compared with those using RSM method. A mathematic model of the intrinsic viscosity of the polymer was established，and the optimized conditions are as follows: 25.41% of mass fraction of monomer, 0.03% of mass fraction of initiator (NaHSO3-(NH4)2S2O4), 26.43 ℃ reaction temperature, 10 h reaction time. In addition, the intrinsic viscosity for polymer is 12.56 dL/g.

Key words: cationic polyacrylamide, intrinsic viscosity, redox initiator, response surface analysis
