Review of Polymerization and Green Polymers Producing in the Supercritical Carbon Dioxide (SC-CO2)

In recent decades, orientations of different sciences are applying the methods which have less effect on the environment and reduce the wastes. For these reasons, producing the polymers with intermediate media (solvent and anti-solvent) of supercritical carbon dioxide is not only a good replacement but also eliminates the problems that were mentioned before. In this article, different processes of homogeneous and heterogeneous polymerization and the polymers which have been produced in this media, have been reviewed. The emulsion polymerizations of water and supercritical carbon dioxide, the polymers applied in the medical purpose and the porous polymers have been studied too. In addition, emulsifiers and stabilizers applied in this field were classified. A review of the research shows the growing and progressing in applying of these solvents, modifying and optimization these methods in the green and sustainable development process.
