Preparation of Fluorinated Copolymers by Copper-Mediated Living Radical Polymerization

Copper-mediated living radical polymerization mediated with pyridine imine ligands has been used for the synthesis of poly(methacrylate)s and polystyrene incorporating fluorinated moieties as either initiators or monomers as well as in the presence of fluorinated solvents. It was found that fluorina...

Description
Summary:Copper-mediated living radical polymerization mediated with pyridine imine ligands has been used for the synthesis of poly(methacrylate)s and polystyrene incorporating fluorinated moieties as either initiators or monomers as well as in the presence of fluorinated solvents. It was found that fluorinated organics do not interfere detrimentally in the polymerization mechanism. α-Perfluoroalkyl initiators have been used for the polymerization of MMA initiated by both 2-perfluoroalkyl ethyl 2-bromoisobutyrate (ZONYL BA initiator) and 2-perfluoroalkyl ethyl-co-poly(ethylene glycol) 2-bromoisobutyrate (ZONYL FSO initiator) initiators which occurs at an almost identical rate to that initiated by ethyl 2-bromoisobutyrate (EIBr). The M n increased linearly with conversion, and the polydispersity indices were low throughout all polymerizations (
