摘　　要：采用氧化还原引发剂(过硫酸铵和甲醛合次亚硫酸钠)与水溶性偶氮引发剂(偶氮二异丁脒盐酸盐)复配的复合引发体系引发丙烯酰胺(AM)与2-丙烯酰胺-2-甲基丙磺酸(AMPS)共聚合成磺化聚丙烯酰胺(SPAM),考察了氧化剂与还原剂配比、复合引发剂配比、聚合引发温度、pH值、单体浓度等条件对聚合物溶液表观黏度的影响,同时对其进行了耐温抗盐性能评价。结果显示,与工业上使用的部分水解聚丙烯稀酰胺(HPAM 3 500万)相比,合成的SPAM具有更好的耐温抗盐性能。The copolymer（sulfonated polyacrylamide） of acrylamide（AM） and 2-acrylamide-2-methyl propane sulfonic acid（AMPS） were synthesized by using a complex initiation system which contains the redox initiator（ammonium persulfate and formaldehyde sulfoxylate sodium sulfite） and water-soluble azo initiator（azobisisobutylamidine hydrochloride）.The effect of redox ratio,complex initiation ratio,reaction temperature,pH of the system,monomer concentration on the apparent viscosity of polymer solution were studied and the temperature tolerance and salt resistance were evaluated.The results showed that the SPAM had better temperature tolerance and salt resistance performance than industrial partially hydrolyzed polyacrylamide（HPAM 3.5×107）.
