  • Publication number: 20220073662
    Abstract: Copolymer compositions and methods of making copolymer compositions with enhanced stability in high temperature and high salinity environments. The copolymers include hydrophobic monomers and sulfonated monomers. The sulfonated monomers can include 2-acrylamido-2-methylpropane sulfonic acid and allyl sulfonate. The sulfonated monomers increase the stability of the polymers in harsh conditions, and in high temperature, high salinity environments. The sulfonated monomers also reduce or prevent the hydrolysis of acrylamide groups, and therefore enhance the stability of the copolymer. The copolymer compositions can be made with free radical polymerization and an initiation complex.
