Green synthesis of polymers using supercritical carbon dioxide

Supercritical carbon dioxide is the most extensively studied supercritical fluid (SCF) medium for polymerization reactions and organic transformations. This can be attributed to a list of advantages ranging from solvent properties to practical environmental as well as economic considerations. Aside from these gains, CO2 finds particularly advantageous application in the synthesis and processing of fluoropolymers and porous materials and as such, this will be the subject of this review. The overall aim is to highlight areas where the unique properties of SCF solvents can be exploited to generate polymers that would be difficult or inconvenient to obtain by other routes.
