Polymer production and processing using supercritical carbon dioxide

Abstract Carbon dioxide plays a vital role during the synthesis and processing (modification) of polymers. This chapter emphasizes recent advancements in polymer modification using SCO2. The SCO2 is a versatile solvent and finds application during polymer production as well as handling. Polymer production using SCO2 includes various polymerization techniques such as homogeneous polymerization, heterogeneous polymerization, precipitation polymerization, suspension polymerization, and emulsion polymerization. Polymer processing using SCO2 highlights different areas manipulating the property of polymers such as its viscosity, plasticization, tendency to form a microcellular foam, and polymer blends. The application of SCO2 in polymer modification emphasize its purification, dyeing, impregnation, and particle production. Overall, SCO2 can be considered as a good supporting medium for modification of polymers.
