Summary Novel imidazoline-based sulfonate copolymers (noted PAMDSCM and PAMPSCM) were successfully prepared by copolymerization of acrylamide (AM), acrylic acid (AA), 1-acrylamido ethyl-2-oleic imidazoline (ACEIM) with the sodium salts of 3-(diallyl-amino)-2-hydroxypropyl (NDS) or 2-acrylamido-2-methylpropane sulfonic acid (AMPS), respectively. The copolymers were characterized by infrared (IR) spectroscopy, 1H nuclear magnetic resonance (1H NMR) spectroscopy, pyrene fluorescence probe spectroscopy, viscosimetry and thermogravimetry (TG). Both PAMDSCM and PAMPSCM copolymers had excellent high-temperature tolerance in comparison with the same concentration of HPAM, and the residual viscosities were 32.0 mPa s and 31.3 mPa s (viscosity retention rates were 38.8% and 37.1%) at 140 °C, respectively. The copolymers possessed superior long-term thermal stability and their residual viscosity rates were up to 81.8% and 63.8% (52.9 mPa s and 47.1 mPa s) lasting 1.5 hours at 100 °C and 170 s-1, respectively.
