 摘要：以丙烯酰胺(AM)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)、甲基丙烯酸N，N二甲基氨基乙酯(DMAEMA)为单体，采用氧化还原-水溶性偶氮复合引发体系制备AM/AMPS/DMAEMA三元磺化共聚物。利用FTIR与核磁氢谱（1H NMR）对共聚物进行结构表征，进行耐温抗盐性能、抗老化性能、溶解性能与抗剪切性能评价。结果表明：AMPS、DMAEMA的引入能显著改善丙烯酰胺类聚合物的耐温抗盐性能，合成的三元磺化共聚物在80℃、矿化度2%（质量分数）的盐溶液下放置90 d后，其溶液的表观黏度仍能达到11.9 mPa·s，相同条件下工业用部分水解聚丙烯酰胺(3 500万)溶液表观黏度仅为0.9 mPa·s，表现出更好的抗老化性。

Abstract: A tetra-polymer AM/AMPS/DMAEMA was synthesized from acrylamide (AM), 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) by a co-initiator system which is composed of redox initiator and water-soluble azo initiator. The structure of tetra-polymer was characterized by infrared (IR) spectroscopy and 1H NMR. The temperature resistance, the salt tolerance, the dissolve performance and the shear resistance were studied. The results showed that the introduction of AMPS and DMAEMA significantly improved the thermal and salt resistance of acrylamide polymers. The AM/AMPS/-DMAEMA solution showed higher apparent viscosity (11.9 mPa·s) than industrial partially hydrolyzed polyacry-lamide (molecular weight of 35 milions) solution(0.9 mPa·s) in the solution of 2% total salinity after 90 d at 80 ℃, which indicated that the solution of AM/AMPS/DMAEMA exhibited better thermal stability.
