Dispersion nitroxide mediated polymerization of methyl methacrylate in supercritical carbon dioxide using in situ formed stabilizers

Controlled dispersion nitroxide mediated polymerization (NMP) of methyl methacrylate (MMA) was successfully carried out in supercritical carbon dioxide (scCO2) in the presence of a CO2-philic perfluorinated stabilizer generated “in situ”. This is an efficient green approach for preparing free flowing PMMA powder consisting of small sized microspheres.
