“…This hypothesis is confirmed by previous studies 9. 10 The authors have performed radical cotelomerization of vinyl ethers and fluoro‐olefin with thiols. By isolating monoadducts, they obtained evidence of the structure of these cotelomers by NMR analyses.…”

“…The NMR results did not permit us to distinguish between the mechanisms. As Boutevin et al 9 and Beaune et al 10 did, we used elementary analysis to determine the composition of copolymers at the beginning of the reaction. In Table 7, we have listed the percentages of each element using the theoretical alternating formula and also the experimental results.…”

The photoinitiated copolymerization of chlorotrifluoroethylene (CTFE) with several vinyl ethers [ethyl vinyl ether (EVE), 2‐chloroethyl vinyl ether (CEVE), cyclohexyl vinyl ether (CHVE), 4‐hydroxybutyl vinyl ether (HBVE)] was studied. CTFE is an acceptor monomer (e ∼ 1.5) whereas vinyl ethers are donor monomers (e ∼ −1.5), and therefore their copolymerization led to alternating copolymers, as indicated by elementary analysis. The equilibrium constant (KF) of the charge‐transfer complex formation (CTC) was determined by 19F NMR spectroscopy. Under our experimental conditions, KF was low for CHVE/CTFE and HBVE/CTFE systems, 0.058 and 0.013 l mol−1 respectively. It can be assumed that the copolymerization involves the free monomers rather than propagation via the donor–acceptor complex. The alternating structure arises from the great difference in polarity between the two types of monomers. Several functional copolymers were prepared in good yield and with molecular weight close to 15 000 g mol−1. © 2002 Society of Chemical Industry

“…This method which was efficient for unsaturated compounds with long hydrocarbon chains (R = C 8 H 17 , C 12 H 25 , C 18 H 37 [6]) was not suitable for compounds such as C 6 F 13 (CH 2 ) 2 -O-CH 2 -CH CH 2 [2].…”

“…The laboratory of macromolecular chemistry in Montpellier was involved for many years in the synthesis of phosphonic compounds with fluorinated or hydrocarbon chains of various lengths C n H 2n+1 P(O)(OR) 2 and C n F 2n+1 -C 2 H 4 -P(O)(OR) 2 [1][2][3][4][5]. Studies were focused on two main routes of synthesis: reactions involving phosphonation [6] or telomerization.…”
