“…132 Chain-end modification with trimethylsilyl groups was even more effective in this regard. 133 Although the solubility of high molecular weight PPO is extremely limited, the use of PPO-based amphiphilic statistical, diblock, and triblock copolymers in sc-CO 2 has attracted considerable attention due to their commercial availability under the Pluronics trademark.…”

“…Therefore, the modification of terminal hydroxyl groups into ether or acetate moieties represents another way of improvement as these groups additionally provide favorable LA–LB interactions with CO 2 . , Thus, PPO samples capped with a butyl ether and an acetate group were more soluble than a diol-terminated PPO in neat CO 2 at 22 °C (see Figure ). Chain-end modification with trimethylsilyl groups was even more effective in this regard …”

This Review provides comprehensive guidelines for the design of CO2-philic copolymers through an exhaustive and precise coverage of factors governing the solubility of different classes of polymers. Starting from computational calculations describing the interactions of CO2 with various functionalities, we describe the phase behavior in sc-CO2 of the main families of polymers reported in literature. The self-assembly of amphiphilic copolymers of controlled architecture in supercritical carbon dioxide and their use as stabilizers for water/carbon dioxide emulsions then are covered. The relationships between the structure of such materials and their behavior in solutions and at interfaces are systematically underlined throughout these sections.

“…The solubility of modified PPO derivatives has been investigated and found that the solubility of modified PPO molecules is strongly influenced by the end groups and their molecular weight. A PPO derivative with a trimethylsilyl (TMS) end group has a higher solubility than one with an Ac end group 26 …”

Poly(vinyl acetate) (PVAc) could be dissolved in CO 2 at a high pressure, which limits its application. In this work, the PVAc-polyether block copolymers were constructed by introducing the CO 2-philic blocks poly(propylene oxide) (PPO) and poly(ethylene oxide) (PEO) into the PVAc molecules to increase the solubility of these polymers in supercritical CO 2 (scCO 2). The dissolution behaviors of PVAc-polyether copolymers with different structures in scCO 2 were investigated by the molecular dynamic simulation methods. First, the cohesive energy and solubility parameters of PVAc, PVAc-PEO, and PVAc-PPO copolymers were analyzed. Moreover, the mechanism of PVAc-polyether copolymers dissolving in CO 2 was investigated. The results show that PVAc-PPO molecules have a higher solubility in CO 2 because they have lower polymerpolymer and higher polymer-CO 2 interactions than PVAc and PVAc-PEO. Among the three structures of PVAc-PPO molecules, PVAc-PPO-PVAc (VPV) has a highest solubility in CO 2. Therefore, the molecular composition and structure have greatly influences on the interactions of polymer and CO 2 .

“…A lot of methods have been developed to determine the solubility of compounds in ScCO 2 . Among them, the cloud point method is an easy and effective way to determine the solubility, and it has been applied to measure the solubilities of compounds in ScCO 2 by a lot of researchers, − as well as by our previous studies. − …”

Paeonol shows a wide range of pharmacological activities in the pharmaceutical industry. In this study, the solubility of paeonol in supercritical carbon dioxide (ScCO2) is determined by measuring the cloud-point pressures of the binary system in a high-pressure variable-volume view cell at various temperatures (i.e., 313.2, 318.2, 323.2, 328.2, 333.2 K) and pressure range of 8–15 MPa. The results show that paeonol has good solubility in ScCO2, and the solubility increases obviously with decreasing temperature and increasing pressure in the experimental range. Then, four density-based models, namely, Bartle, Méndez-Santiago and Teja, Ch and Madras, and Gordillo, are employed to correlate and predict the solubility data. The relevant average absolute relative deviation values of Bartle, Méndez-Santiago and Teja, Ch and Madras, and Gordillo are 9.05, 9.37, 8.75, and 8.49%, respectively, indicating that the models can well predict the solubility data.
