Emulsion polymerization in supercritical carbon dioxide is a green technology in the synthesis and process of polymer materials. Supercritical carbon dioxide is nontoxic, nonpolluting, easier to be separated, with rapid polyreaction speed and high selectivity. In this paper, the development and the latest advances in the emulsion polymerization in supercritical carbon dioxide are reviewde. It is figured out that supercritical carbon dioxide should be used in the emulsion polymerization to produce synthetic polymer materials without the toxic or volatiole organic solvent. It can reduce the environmental pollution, increase the performance of materials and simplify the process and production technology, with the widespread prospect in application.
