The hydrophobically associating acrylamide/dibutylacrylamide(AM/DBA) copolymers were synthesized by aqueous micellar polymerization for Enhanced Oil Recovery(EOR). The effects of hydrophobe and surfactant content on the dissolution behavior of the copolymers have been investigated. The results show that when the mass fraction of hydrophobic monomer was between 0.8% and 1.0%, and the N_H value was between 8 and 10, the copolymers showed both good solubility and salt-tolerance, and their filter ratio were less than 2. The contradiction between solubility and salt-tolerance of copolymers could be well settled e.g. the copolymer having intrinsic viscosity exceeding 22 dL/g can be dissolved in water for 2 h giving the solutions characteristic of salt-viscosifying.
