摘      要：Super high molecular weight copolymers of AM/NaA/AMPS were prepared by oxidation–reduction[OR-P(AM/NaA/AMPS)]and controlled radical polymerization[CR-P(AM/NaA/AMPS)].The resulting copolymers were fully characterized,and the reaction conditions for their preparation were ***-P(AM/NaA/AMPS),CR-P(AM/NaA/AMPS),and conventional partially hydrolyzed polyacrylamide(HPAM)in brine solution were comprehensively characterized by thermogravimetric analysis,scanning electron microscopy,atomic force microscopy,and dynamic light ***(AM/NaA/AMPS)and CR-P(AM/NaA/AMPS)containing AMPS monomer showed better salt resistance,temperature tolerance,and viscosification property than the conventional HPAM polymer,making them more promising for enhanced oil *** comprehensive comparison and analysis,it was found that OR-P(AM/NaA/AMPS)was more conducive for high-temperature condition due to the existence of xanthone in OR-P(AM/NaA/AMPS).On the other hand,CR-P(AM/NaA/AMPS)was more suitable for high-mineral atmosphere,which could be attributed to its higher intrinsic viscosity.
