摘　　要：采用NaHSO3-K2S2O8和偶氮二异丁脒盐酸盐(AIBA)复合引发剂体系及高低温分段引发法合成了丙烯酰胺/2-丙烯酰胺基-2-甲基丙磺酸(AM/AMPS)共聚物,通过单因素实验与正交试验考察了单体质量分数、引发剂质量分数、引发温度、pH、单体配比、引发剂配比等因素对共聚物表观黏度的影响,筛选出共聚物的最佳制备条件,即单体质量分数为25%,引发剂质量分数为0.015%,引发温度为10℃,pH=7,m(AM)∶m(AMPS)=5∶1,m(K2S2O8)∶m(NaHSO3)=2∶1,m(NaHSO3-K2S2O8)∶m(AIBA)=1∶1,引发时间为1.5 h。耐温抗盐及热稳定性评价实验结果表明AM/AMPS共聚物的综合耐温抗盐性较好。Copolymer acrylamide/2 -acrylamide -2 -methyl propylsulfonate was synthesized by using aerylamide （ AM ） and 2 - acrylamide - 2 - methylpropane sulfonic acid （AMPS） as starting materials, and adopting high/low temperature two - step initiating method, with a complex initiator system which composed of NaHSO3 - K2 S2 O8 and azo diisobutyl amidine hydrochloride （AIBA）. Factors that affect the apparent viscosity of the product, such as mass fraction of reacting monomers, mass fraction of initiator, temperature, pH, ratio of monomers, ratio of initiator et al were studied by single factor experiment and orthogonal designed experiment. The optimal preparation conditions of polymers were screened as：monomer mass fraction,25% ;initiator mass fraction,0. 015% ;initiation temperature, 10 ℃ ;pH,7 ;m（AM） ： m（AMPS） = 5：1 ;m（ K2S2O8 ） ： m（NaHSO3 ） = 2：1 ; m （ NaHSO3 - K2 S2 O8 ） ： m （ AIBA ） = 1 ： 1 ; initiating time, 1.5 h. Temperature tolerance, salt resistance and thermal stability evaluation experiment results showed that the AM/AMPS copolymer product acts good comprehensive performance.
