    Graphical Abstract
    • Abstract
  • The conformation of polystyrene in the antisolvent process of supercritical fluids (compressed CO2+polystyrene+tetrahydrofuran) is studied by synchrotron radiation Xray small angle scattering(SAXS). Coiltoglobule transform of polystyrene chain is observed with increasing the concentration of CO2. It is found that polystyrene coils at the pressure lower than cloud point pressure (pc) and changes into globule with uniform density at the pressure higher than pc.
