Copolymerization of fluorinated monomers: recent developments and future trends

High molecular weight graft stabilisers for dispersion polymerisation of vinylidene fluoride in supercritical carbon dioxide: the effect of architecture

“…1 H NMR, 19 F NMR and 13 C NMR were performed for the stabilisers and the starting materials using a Bruker 300 MHz spectrometer. Infrared analysis for the fluorinated graft stabilisers and the starting materials (PMVE-MA and PMA-OD) was carried out using a Perkin-Elmer system 2000 FTIR spectrometer equipped with a diffuse reflectance infrared spectroscopy (DRIFTS) attachment (Spectratech).…”

“…5). 19 F NMR analysis (Fig. 6) was also performed for FGS-I-c and PFOL in the mixture of CDCl 3 and octafluorotoluene (50/ 50, v/v).…”

“…This eliminates the necessity for energy-intensive drying procedures. There are some publications on the investigation of free radical (co)polymerisation of VDF by aqueous emulsion and suspension techniques [16][17][18][19][20] [21][22][23], as well as the dispersion polymerisation of VDF using a range of VDF-based copolymers as stabilisers [11]. However, no distinct, spherical particles were obtained.…”

Palladium-Catalyzed Cross-Coupling Reactions of Perfluoro Organic Compounds

“…Alternative routes to synthesize (α,β,β-trifluoro)styrenes via the cross-coupling of chlorotrifluoroethylene with arylboronic acids have recently been reported [36,37]. Against such a background, we started developing a novel strategy for their preparation from 1, because 1 is an economical bulk organofluorine feedstock for the production of poly(tetrafluoroethylene) and co-polymers with other alkenes [38][39][40]. However, to the best of our knowledge, no catalytic reactions involving 1 had been reported until we reported the first catalytic transformation reaction [41], while homogeneous catalytic reactions involving C-F bond activation have received an increasing amount of attention [42][43][44][45][46][47][48][49][50][51][52][53].…”

Fluoroalkyl end-capped oligomers possessing nonflammable and flammable characteristics in silica gel matrices after calcination at 800 °C under atmospheric conditions

“…However, perfluorinated polymers such as poly(tetrafluoroethylene) decompose at higher temperatures (around 600 1C) because of the bond-strengthening effect of fluorine for the C-C and C-F bonds in highly fluorinated compounds. [1][2][3][4][5] From the developmental viewpoint of novel nonflammable materials, hybridizations of these fluorinated polymers with metal alkoxides [6][7][8][9][10] and graphite oxide 11 are of particular interest. In fact, some studies on the hybridization of fluorinated polymers with alkoxysilanes [6][7][8][9][10] have been hitherto reported; however, the thermal stability of these hybrids is in general inferior to that of the original silica gels.…”
