Investigation of phase equilibria and nucleation for supercritical carbon dioxide and model copolymer mixtures

Abstract

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.
