Solubility and Diffusivity of Polyethyl Acrylate in Supercritical Carbon Dioxide

摘要

An alternative plastic-bonded molding powder production process would use a polymeric binder dissolved in supercritical carbon dioxide rather than the liquid organic solvents currently used.This research investigated the solubility and diffusion coefficients of polyethyl acrylate,a potential binder,in supercritical carbon dioxide.Over the range of solvent conditions investigated,the dissolved polymer concentration was 0.036 wt% or less.A practical molding powder production process is not likely with such a dilute binder solution.
