In this work, an equation of state based on the Weeks-Chandler-Andersen WCA perturbation theory was established for the mixture of SC-CO2 and model copolymer. The influences of temperature, pressure and chain length of model copolymer molecules on phase equilibria and critical micelle concentration CMC were investigated.
