Cloud-point behavior of binary and ternary mixtures of PHPMA and PHPA in supercritical fluid solvents

Structure–Property Relationships in CO2-philic (Co)polymers: Phase Behavior, Self-Assembly, and Stabilization of Water/CO2 Emulsions

“…This may be due to the domination of dispersion forces at higher temperatures. These side chain length trends were further investigated in different studies focusing on poly­(alkyl acrylates), such as poly­(propyl acrylate), poly­(hydroxypropyl acrylate), poly­(hexyl acrylate), poly­(cyclohexyl acrylate), poly­(2-ethylhexyl acrylate), poly­(isooctyl acrylate), poly­(decyl acrylate), poly­(dodecyl acrylate), and poly­(octadecyl acrylate) …”

Cloud-Point and Bubble-Point Measurement for the Poly(2-butoxyethyl acrylate) + Cosolvent Mixture and 2-Butoxyethyl Acrylate in Supercritical Fluid Solvents

“…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.…”

Yang et al reported cloud-point behavior of binary and ternary mixtures of poly­(hydroxypropyl acrylate) + SCF solvent + cosolvent system. In this system, the pressure–temperature diagram changes from an upper critical solution temperature (UCST) region to a lower critical solution temperature (LCST) region as the cosolvent concentration is increased at temperatures between (323 to 455) K and pressures up to 175 MPa.…”
