When CO2 is dissolved into a polymer, several polymer properties are drastically changed. In this article, solubility and diffusivity of CO2 in several molten state thermoplastics as well as some rubbers are discussed. In addition to illustrating the solubility and diffusivity data of CO2 into polymers, the data of CO2 induced depression of glass transition temperature as well as viscosity are introduced.
