Phase behavior of poly(dimethylsiloxane)-poly(ethylene oxide) amphiphilic block and graft copolymers in compressed carbon dioxide

► Phase behavior of triblock and graft copolymers of PDMS and PEO in compressed CO2. ► Cloud-point pressures measured from P = 10 to 40 MPa and T = 293 to 338 K. ► Perturbed-chain statistical association fluid theory (PC-SAFT) has been applied. ► A temperature-dependent binary interaction parameter kPDMS-CO2 has been used.
