Solubility, diffusivity and viscosity in supercritical fluid and polymer systems are reviewed. Supercritical fluids such as carbon dioxide dissolve in polymers at high pressures and plasticize them. The increase in diffusivity and the decrease in viscosity of polymers with dissolved supercritical fluids are due to the plasticizing effect of supercritical fluids. In this article general tendency, data source and theoretical calculation methods of solubility, diffusivity and viscosity are presented for supercritical carbon dioxide and nitrogen in polymers.
