Nitroxide‐mediated stabilizer‐free inverse suspension polymerization of <i>N</i>‐isopropylacrylamide in supercritical carbon dioxide

Abstract

The first inverse dispersed phase controlled/living polymerization in supercritical carbon dioxide (scCO2) is described. The nitroxide-mediated radical polymerization of N-isopropylacrylamide proceeded in the absence of stabilizer to high conversion giving a dry powder. The polymerization and purification does not require the use of environmentally damaging volatile organic compound.
