“…[17] Usually,m ost fluorinated homopolymers exhibit ac ouple of drawbacks, e.g.,( per)fluorinated homopolymers have ah igh crystallinity rate (mainly linked to the symmetryo fm onomer units), whichi mparts al ow solubility in common organic solvents (thus hampering their chromatographic, viscosimetric and some spectroscopicc haracterizations) and their crosslinking can be difficult. That is why the generation of fluorinated copolymers [18] (composed of mixture of comonomers that can insert bulky side-groups inducing some disorder in the macromolecule hence reducing or getting rid of the high crystallinity of homopolymers) has not stopped increasing without having the drawbacks of aforementioned homopolymers.…”

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.

Conventional and RAFT Copolymerization of Tetrafluoroethylene with Isobutyl Vinyl Ether

et al. 2018

The solution copolymerizations of tetrafluoroethylene (TFE) with isobutyl vinyl ether (iBuVE), using both conventional radical and RAFT/MADIX methods are presented. O-Ethyl-S-(1-methyloxycarbonyl)ethyl xanthate and benzoyl peroxide (BPO) were used as RAFT chain transfer agent and initiator, respectively, in dimethyl carbonate. Degrees of polymerization ca. 20 were targeted. In all cases, alternating copolymers were obtained. Poly(TFE-alt-iBuVE) copolymers synthesized via conventional radical copolymerization using from 1 to 30 mol % BPO exhibited molar masses varying between 11000 and 4400 g•mol-1 , respectively, and broad dispersities (Ð = 2). Poly(TFE-alt-iBuVE) copolymers synthesized by RAFT/MADIX had molar masses ranging from 1200 to 2000 g•mol-1 at 15 min to 24 hrs, respectively, and more narrow Ðs (1.08 and 1.11, respectively). The ratio of chain ends is nearly time invariant, with a slight

“…Fluorinated polymers are niche macromolecules that play an essential role in modern life [1], and due to the properties of fluorine (including, among others, large electronegativity, low polarizability, and a small van der Waals radius of 1.32 Å) and the strong C−F bonds (485 kJ•mol −1 ), they exhibit unique and remarkable properties [2]. Their applications span engineering thermoplastics and elastomers for the chemical-process, automotive and aeronautics industries, weather-proof coatings, biomedical materials, separators, electrolytes, binders for Li-batteries, exchange membranes in fuel cells, and many more [1,[3][4][5][6][7][8][9][10][11][12]. Poly(tetrafluoroethylene) (PTFE) discovered in 1938 by Roy Plunkett [13], was the first fluoropolymer to be commercialised and has played a major role in many high-tech applications throughout its 80 year history.…”
