In this paper, the synthesis of zwitterionic copolymers for enhanced oil recovery (EOR) was studied in detail. The copolymers were synthesized via free-radical copolymerization. Different molar ratios (2:98, 10:90, 20:80, 30:70) of zwitterionic sulfobetaine-N-(3-dimethylamino)propyl methacrylamide (P(SB-DMAPMA)) copolymerized with acrylamide (AM). Resulted in copolymers characterized by nuclear magnetic resonance (NMR) and Fourier Transform Infrared Spectroscopy (FTIR). The molecular weight of copolymers was measured with the Static Light Scattering method. Reactivity ratios of the monomers were calculated using three methods: Fineman-Ross, Kelen-Tudos, and Mayo-Lewis. The study also discussed the thermal stability of zwitterionic copolymers and rheological properties in pure water and in high-salinity conditions with different charges. Increased viscosity after adding different salts was analyzed by rheological measurements, and the images of structures of molecules were taken by Transmission Electronic Microscope (TEM). The findings of this study can be useful to enhance the efficiency of EOR processes, paving the way for more advanced oil recovery techniques.
