摘　　要：以丙烯酰胺 (AM)、N 乙烯基 2 吡咯烷酮 (VP)和 2 丙烯酰胺基 2 甲基丙磺酸 (AMPS)为单体 ,以水作为溶剂 ,在反应温度 6 0～ 6 5℃ ,pH值为 8左右 ,反应时间为 8h的条件下合成了AM-VP -AMPS共聚物。用IR、13 CNMR对共聚物结构进行了表征 ,研究了共聚物溶液的耐温抗盐性能。结果表明 :少量的阳离子会导致共聚物的水溶液黏度急剧下降 ,当阳离子量达到一定值后 ,继续增加阳离子量对共聚物的水溶液黏度影响不大 ,共聚物的标准盐溶液在温度 (90± 1 )℃无氧的条件下老化 1 30天 ,其溶液黏度的绝对值仍然在 6 0mPa·s以上。AM-VP-AMPS copolymer was prepared by aqueous solution polymerization with AM,VP,and AMPS as comonomers under such conditions as reaction temperature 60-65 ℃,pH value about 8 and reaction time 8h.Structure of the copolymer was identified by IR and 13 CNMR spectra.Tolerance to high temperature and salt of the copolymer solution was studied.The result showed that a little amount of cation could lead an abrupt decreasing of apparent viscosity for aquesous copolymer solution.When the content of cation reached a certain value,further increase of cation had little effect on apparent viscosity of aqueous copolymer solution.After aging 130 days at (90±1) ℃ under oxygen free condition,the apparent viscosity of standard salt solution of the copolymer was still greater than 6 0 mPa·s.
