Supported ATRP of fluorinated methacrylates in supercritical carbon dioxide : preparation of scCO2 soluble polymers with low catalytic residues

Synthesis of poly( 2,2,2-trifluoroethyl methacrylate) by supported ATRP was investigated in supercritical carbon dioxide using a copper salt ligated to a polymeric ligand immobilised onto silica; after polymerisation, fluorinated polymers with well defined molecular weight and low polydispersity were obtained
