| 摘 要： | 在过硫酸铵((NH4)2S2O8)-亚硫酸氢钠(NaHSO3)氧化还原体系下合成了丙烯酰胺(AM)/2-丙烯酰胺基-2-甲基丙基磺酸(AMPS)/N-烯丙基油酰胺(CON)三元共聚物。最佳反应条件为:单体配比m(AM)∶m(AMPS)=9∶1,CON加量0.33%,引发剂0.4%,pH值为7,温度40℃,反应8h。对AM/AMPS/CON共聚物进行了红外和特性黏数(621mL/g)表征;当NaCl质量浓度为12g/L时,AM/AMPS/CON三元共聚物的黏度保留率能达到36.67%,当MgCl2,CaCl2质量浓度为1.2 mg/L时,共聚物的黏度保留率分别为48.24%,41.75%;温度为120℃时,AM/AMPS/CON三元共聚物粘度保留率达43%。

| Abstract: | Hydrophobically associating copolymers of acrylamide(AM),2-acrylamido-2-methylpropanesulfonic acid(AMPS)and N-allyl base oil amides(CON)were synthesized by free radical polymerization in the presence of(NH4)2S2O8-NaHSO3 as initiator.The optimized conditions were built: m(AM)∶m(AMPS)=9∶1,initiator was 0.4%,pH was 7,temperature was 40 ℃ and reaction time was 8 h.The structure of the copolymer was characterized by IR.The intrinsic viscosity number of the copolymer was about 621 mL/g.The AM/AMPS/CON copolymer solution viscosity retention rate were about 36.67%,48.24%,41.75% when the concentrations of NaCl,MgCl2,CaCl2 were 12 000 mg/L,1 200 mg/L,1 200 mg/L,respectively.The viscosity retention rate was 43% when the temperature was up to 120 ℃. |
