In this work, cloud-point and bubble-point phase behavior data are reported for the poly(dimethylsiloxane)[PDMSA] in supercritical carbon dioxide, propane, propylene, butane, 1-butene and dimethyl ether (DME). The static-type method, using a variable-volume view cell, was employed to obtain the experimental data at the temperature range for (315.2-454.9) K and pressure up to 55.52 MPa. PDMS (Mw = 38,900) + C4 cloud-point curves are ~10 MPa lower than the PDMS + C3 curves at constant temperature of 423 K. Cloud-point curves for the PDMS + solvents system show the lower critical solution temperature (LCST) region.

Keywords:Poly(dimethylsiloxane);Supercritical solvents;Phase behavior;LCST
