Though many studies deal with the controlled radical polymerization (or RDRP) of styrene and acrylate monomers, a few works have been achieved on that of fluorinated monomers. RDRP of vinylidene fluoride (VDF) has been very rarely reported.1-3 The synthesis of PVDF using MADIX solution polymerization was thus investigated in details: Solution polymerization afforded well-defined PVDF.1-3 The careful polymer chain-end monitoring using MALDI-TOF as well as 1H, 19F, and HETCOR 1H-19F NMR nonetheless revealed that VDF reverse additions and transfer to solvent reactions affect the control of the polymerization.1,2 Then, explored attempts to reinitiate further chains led to original graft copolymers,2 block copolymers,1,3 and dendrimers. More recently, Cobalt-mediated radical polymerization of VDF led even to a better control and is compared to above strategies.4 (1) M. Guerre, B. Ameduri, R. Poli, and V.
