Polymer processing in supercritical fluids has been a major interest for a portfolio of materials processing applications including their impregnation into porous matrices. Unfortunately they are only sparingly soluble in CO2 unless one uses an entrainer or surfactant. This work focuses their solubility at rather mild conditions, low temperature and reduced pressures less than three. Solubility of poly methyl methacrylate (PMMA) in CO2 plus methyl methacrylate is determined using cloud point measurements. The results are modeled accurately using SAFT.
