Recently the use of sub/supercritical CO2 has received much attention as a green alternative to organic solvents for chemical processes because of its pressure-tunable physicochemical properties and economic advantages. But, the advantages are diminished because of a narrow range of CO2-soluble materials. The goal of this work is to identify and design oxygenated hydrocarbon-based CO2-soluble polymers that are able to serve as construction blocks for CO2 soluble materials. Without concerning on the cost and the environmental persistence like fluorinated materials, the inexpensive and...
