Telomerization of bis(trifluoromethyl)disulfide with polyfluoro-olefins

Kinetics of radical telomerization of vinylidene fluoride in the presence of CCl3Z chain transfer agents

“…Such an observation was already noted for the addition of C n F 2n+1 (n = 4, 6, 8) [26][27][28], RS [29,30], (EtO) 2 P (= O) [31] radicals onto VDF. VDF:HCCl 3 and VDF:CCl 4 monoadducts were also synthesized but, unlike BrCCl 3 , their syntheses required higher initial CTA concentrations.…”

Fluorinated cotelomers based on vinylidene fluoride (VDF) and hexafluoropropene (HFP): Synthesis, dehydrofluorination and grafting by amine containing an aromatic ring

“…The telomerization of vinylidene fluoride has been extensively investigated [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Perfluoroalkyl iodides or a,v-diiodoperfluoroalkanes act as efficient chain transfer agents (CTA), since they easily undergo CF 2 -I bond cleavage [5,6,9,11,12,14,15,[20][21][22] leading to low molecular weight molecules.…”

Synthesis and copolymerization of vinylidene fluoride (VDF) with Trifluorovinyl Monomers, 11

“…The telomerization of vinylidene fluoride (VDF) (or 1,1‐difluoroethylene) has been carried out by many authors and was recently reviewed 1. Various transfer agents have been utilized: hydroxylated,2,3 sulfurated,4–6 phosphorated7,8 and polyhalogenated 9–14. Among these latter telogens, the brominated ones do not have the same fate as the iodinated ones.…”
