Abstract The catalytic polymerization of ethylene is performed in water pressurized with CO 2 . The size of the initial monomer droplets and of the resulting polymer particles can be varied by simply changing the CO 2 pressure. Furthermore, at identical ethylene partial pressure, the polymerizations performed in the presence of CO 2 are significantly faster than in its absence. Thus, the combination of CO 2 and water is a promising green solvent for catalytic emulsion polymerizations.
