Abstract: The tercopolymer AM-AMPS-N8AM was prepared through radical polymerization with 1-butyl-3-methyl imidazolium tetrafluoroborate ionic liquids as the reaction medium of polymerization, benzoperoxide/N,N-dimethylaniline(BPO/DMA) redox system as the initiator, acrylamide(AM) and 2-acrylamido-2-methylpropane sulfonic acid(AMPS) as the hydrophilic monomer, N-octylacrylamide(N8AM) as the hydraphobic monomer. The structure of polymer was identified by 1H NMR, 13C NMR and element analysis. The apparent viscosity of the terpolymer aqueous solution is measured, and the result shows that the terpolymer synthesized in ionic liquids has an excellent tackifying ability.When the mass concentration of solution is 1.2 g/L, the apparent viscosity can reach 220.1 mPa·s, when the temperature changes from 45 ℃ to 90 ℃, the viscosity remaining rate is 65% and when the shear rate increases to 24.48 s-1, the viscosity remaining rate is 43.5%. It is shown that the tercopolymer solution has better temperature tolerance and shearing resistance
