“…Our group has demonstrated that phase behavior for a binary system consisting of a polymer in SCF solvent shifted to lower temperatures and pressures upon the addition of cosolvent in the mixtures. ,− Byun and Lee reported the experimental cloud-point data for the poly(decyl acrylate) + CO 2 + decyl acrylate (or DME) mixtures at temperatures up to 478 K and pressures up to 230 MPa . Yang et al reported cloud-point behavior of binary and ternary mixtures of poly(hydroxypropyl acrylate) + SCF solvent + cosolvent system.…”

“…Lee et al 10 reported the binary and ternary mixtures for the poly(dodecyl acrylate) + propane, + propylene, + butane, + 1-butene, and + dimethyl ether, as well as for the poly(dodecyl acrylate) + dodecyl acrylate (or DME) in SCF CO 2 at temperatures ranging from 315 K to 464 K and pressure up to 205 MPa. Jang et al 11 reported the monomer impact on the cloud-point behavior for the poly(benzyl acrylate) in supercritical CO 2 and dimethyl ether.…”

High pressure cloud-point data were reported for poly-(2-butoxyethyl acrylate) [P(2-BEA)] in propane (C 3 H 8 ), propylene (C 3 H 6 ), butane (C 4 H 10 ), 1-butene (C 4 H 8 ), and dimethyl ether (DME) (CH 3 OCH 3 ), as well as for the P(2-BEA) + 2-butoxyethyl acrylate (2-BEA) (or DME) system in supercritical CO 2 . Cloud-point pressures for the P(2-BEA) + C 3 hydrocarbons curves were ca. 22 MPa higher than those for P(2-BEA) + C 4 hydrocarbons, at a constant temperature of ca. 393 K. The cloud-point pressure for the P(2-BEA) + DME system was located between C 3 and C 4 hydrocarbons at pressures below ca. 20.0 MPa. The P(2-BEA) + CO 2 + 0.649 and 0.680 2-BEA phase behavior curves intersect a one phase (fluid) → two phases (liquid + vapor) curve at temperatures of 353.6 K (at 24.5 MPa) and 413.4 K (at 32.3 MPa). The location of the P(2-BEA) + CO 2 cloud-point curve shifts to lower temperatures and pressures upon the addition of 2-BEA or DME. Vapor−liquid phase equilibrium data at high pressures were presented for the CO 2 + 2-BEA system at temperatures ranging from (313.2 to 393.2) K and pressures up to 20.38 MPa. The CO 2 + 2-BEA system exhibits type-I phase behavior with a continuous critical mixture curve and was adequately modeled using the Peng−Robinson equation of state.

“…Recently, we have demonstrated that it is possible to dissolve poly(acrylate) and poly(methacrylate) in supercritical fluid solvents over a wide range of temperatures at high pressure [5,6]. Also, Chalykh and Avdeyev [7] have reported the phase equilibrium of binary mixture for the polyethylene + PDMS system.…”
