“…Extensive research on the development of RDRP techniques all over the world has led to the development of nitroxide-mediated polymerization (NMP), [42] atom transfer radical polymerization (ATRP), [26] ITP, [33,43] RAFT, [44][45][46] including macromolecular design via interchange of xanthates (MADIX) polymerization, [30,47] organoheteroatom-mediated radical polymerization based on tellurium, bismuth, antimony [48] and organometallic-mediated radical polymerization (ORMP). [49] Chung and co-workers [50,51] reported the synthesis of end-functionalized fluoropolymers via RDRP using functional borane initiators. Recently, Goto's team [52,53] developed reversible complexation mediated RDRP, but not applied to fluorinated monomers.…”

“…Chung [50] studied the radical polymerization of fluoroalkenes (especially VDF) controlled by boranes, the mechanism being supplied in Scheme 3. Results revealed that the borane/oxygen controlled radical initiators is surprisingly effective for initiating polymerization of different fluorinated monomers, including VDF, TrFE and CTFE, at ambient temperature.…”

“…Synthesis of PVDF mediated by borane/oxygen based radical initiators. [50] Organotellurium CTAs are usually prepared under basic conditions. The reaction of alkyl or aryl lithium reagents with tellurium metal affords the corresponding organotellanyl lithium species, which reacts with organochlorides, bromides, and iodides to give the desired CTA.…”

“…Chung comprehensively used that strategy for the polymerization of many monomers, including fluorinated alkenes such as VDF, CTFE and TrFE in which RO • peroxy radical initiates the polymerization while • OBR acts as a counter radical stabilized by the back donating effect on the radical from  orbital. [50,51,92,93] Zhang et al [92] reported borane mediated synthesis of PVDF for potential application in high energy density capacitors (Scheme 8). The results revealed that the borane/oxygen system controlled radical initiators are surprisingly effective for initiating polymerization of fluorinated monomers.…”

An overview on fluorinated olefins-based architectures prepared by reversible deactivation radical polymerization (RDRP) techniques and applications is presented. Controlled synthesis of well-defined fluoropolymers is discussed as a route to prepare tailored macromolecules of various architectures, such as homopolymers, block copolymers (BCPs), graft copolymers, and star/miktoarms[1]. Primary examples of different strategies of synthesis include (a) Iodine Transfer Polymerization (ITP), (b) Reversible Addition-Fragmentation Chain Transfer /Macromolecular Design via the Interchange of Xanthates (RAFT/MADIX) polymerization, (c) Atom Transfer Radical Polymerization (ATRP), (d) Nitroxide Mediated Polymerization (NMP), (e) Organometallic-Mediated Radical Polymerization (OMRP) and (f) Others systems (based on borinates, Tellurium, and other complexes). Synthesis of BCPs and graft copolymers using these polymerization techniques of vinylidene Fluoride (VDF), chlorotrifluoroethylene (CTFE) and other fluorinated monomers was also discussed, as well as using Copper(I)-catalyzed azide-alkyne cycloaddition (click chemistry). Phase behavior and self-assembly of the fluorinated block copolymers were also discussed. Special attention was devoted to the applications of fluoropolymer architectures in producing thermoplastic elastomers, medical tactile sensors, fuel cells membranes, functional coatings, electroactive polymers (e.g. piezoelectric/ferroelectric/dielectric devices and actuators), high energy storage capacitors, surfactants and composites.

“…But, for fluoropolymers, the situation appears reversed since ITP of fluoroalkenes already led to commercially available TPEs as soon as 1984 (Daiel® commercialized by the Daikin company (Scheme ), [34] followed by Viton® and Tecnoflon®, marketed by Dupont (now Chemours) and Solvay Solexis (now Solvay Specialty Polymers), respectively. Overviews on RDRP of fluorinated monomers were reported via ITP or from techniques involving either borinates or xanthates (named RAFT/MADIX technology) …”

An overview on the synthesis, properties, and applications of fluoropolymers (PFs) is presented. First, a non-exhaustive summary on the homopolymers from conventional radical polymerization of fluoromonomers is proposed. FPs are interesting materials thanks to their outstanding properties such as thermal, oxidative and chemical resistances, low dissipation factor, refractive index, permittivity, and water absorptivity, as well as excellent durability and weatherability. Various strategies of synthesis are proposed, especially on recent studies on radical (co)polymerization of fluoroalkenes, just like their properties and applications ranging from coatings and energy-related materials (e.g. fuel cell membranes, components for lithium ion batteries, electroactive devices, and photovoltaics) to original fluorinated elastomers, surfactants, thermoplastic elastomers, thermostables, and optical devices.

This article aims at showing the usefulness of fluoropolymers (FPs), supplying an overview of their synthesis, applications, and recycling. FPs are currently prepared by conventional radical polymerization of fluoromonomers. These specialty polymers, produced in low tonnage compared to that of commodity ones, display outstanding properties, such as chemical, oxidative, and thermal resistances, low refractive index, dissipation factor, permittivity, and water absorptivity, and excellent weatherability and durability. More recent routes for their preparations are suggested, controlled or not, leading to random, alternated, block, graft, dendrimers, or multiarm copolymers, as well as their applications ranging from coatings to high performance (thermoplastic) elastomers, energy related-materials (e.g., fuel cell membranes, components for lithium-ion batteries, electroactive devices, and photovoltaics) to original and surfactants, optical devices, organic electronics, composites, and shape memory polymers.
